And if we want all the data, we need to ease people into it. Let them add it later. Add features that encourage them to share more and more information over time. So let's start with a simple model of a user. They must have a name, but we are going to make the age optional.

I wonder if they really care about her Later Tom creates a profile and does give his age:. Great, that will be nice on his birthday. But more importantly, Tom is part of a valuable demographic! The advertisers will be pleased. Alright, so now that we have some users, how can we market alcohol to them without breaking any laws?
People would probably be mad if we market to people under 21, so let's check for that:. Notice that the Maybe type forces us to pattern match on the users age. It is actually impossible to write code where you forget that users may not have an age. Elm makes sure of it!
Now we can advertise alcohol confident that we are not influencing minors directly!
Maybe (Brainstorm song)
Only their older peers. This Maybe type is quite useful, but there are limits. Beginners are particularly prone to getting excited about Maybe and using it everywhere, even though a custom type would be more appropriate. For example, say we have an exercise app where we compete against our friends.
What does maybe mean?
You might be tempted to model it like this:. All the information is there, but you are not really modeling the way your particular application works. It would be much more precise to model it like this instead:. This new model is capturing much more about your application. There are only two real situations. Either you have just the name, or you have the name and a bunch of information.
In your view code, you just think about whether you are showing a Less or More view of the friend. Point is, if you find yourself using Maybe everywhere, it is worth examining your type and type alias definitions to see if you can find a more precise representation.

This often leads to a lot of nice refactors in your update and view code! I call it my billion-dollar mistake. It was the invention of the null reference in My goal was to ensure that all use of references should be absolutely safe, with checking performed automatically by the compiler. But I couldn't resist the temptation to put in a null reference, simply because it was so easy to implement. This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years.
That design makes failure implicit. Any time you think you have a String you just might have a null instead. Should you check? Government must anticipate the broad strokes of future structural shifts. New technologies—including robotization and artificial intelligence— represent further challenges. Recent and earlier episodes of such changes have generated one important lesson: the market on its own is not up to the task.
There is a simple reason already explained: those most affected, for instance, those who are losing their jobs, are least able to fend for themselves. The changes often imply that their skills are less valuable.

They may have to move to where the jobs are being created—and house prices in the growing parts of the country are often far higher. Thus, there is an essential role for government to facilitate the transition, through what have been called active labor market policies. Such policies help retrain individuals for the new jobs and help them find new employment.
Another tool for government is referred to as industrial policies, which help restructure the economy into the directions of the future and assist the creation and expansion of firms, especially small and medium-sized enterprises in these new sectors. Some countries, like those in Scandinavia, have demonstrated that well-designed active labor market and industrial policies can create jobs as fast as jobs get destroyed and can move people from the old jobs to the new. There have been failures, but that is because sufficient attention has not been paid to what makes for successful policies.
As government pursues labor market and industrial policies, it needs to be sensitive to questions of location. Too often economists ignore the social and other capital that is built into a particular place. When jobs leave a place and move elsewhere, economists sometimes suggest that people should move too.

But for many More generally, decisions about where to locate are not efficient. Too many people may want to crowd into the big urban centers, causing congestion and putting strains on local infrastructure. Among the reasons that factories moved to rural areas But some of the same forces that had led to low wages are now contributing to the problem of deindustrialization.
Wages were low in part because of lack of mobility—with perfect mobility, wages skill-adjusted would be the same everywhere. But this lack of mobility is key to understanding why deindustrialization is so painful.
In short, we need policies focusing on particular places cities or regions going through stress , in what are called place-based policies, to help restore and revitalize communities. Some countries have managed such policies extraordinarily well: Manchester, England, the textile capital of the world in the nineteenth century, has reinvented itself—with help from the UK government—as an educational and cultural center. It still may not be as relatively prosperous as it was in its heyday, but it is instructive to compare Manchester with Detroit, which the United States simply let go bankrupt.
Government played a central role in the transition from agriculture to a manufacturing economy; it now needs to play a similar role in the transition to the new economy of the twenty-first century. One of the most important detractors from individual well-being is a sense of insecurity. Those who feel more secure can undertake riskier activities, often with higher payoffs. In our complex society, we are constantly confronting risks. New technologies may take away jobs, even if they also provide new ones. Climate change itself presents untold new risks, as we have recently experienced with hurricanes and fires.
Again, large risks like these and ones associated with unemployment, health, and retirement, are risks that markets do not handle well. In some cases, like unemployment and health insurance for the aged, markets simply do not provide insurance; in other cases, like retirement, they provide annuities only at high costs, and even then, without important provisions—such as adjustments for inflation.
That is why almost all advanced countries provide social insurance to cover at least many of these risks. Governments have become fairly proficient in providing this insurance—transaction costs for the US Social Security system are a fraction of those associated with comparable private insurance.
Maybe (Sick Puppies song)
We need to recognize, however, that there are large gaps in our system of social insurance, with many important risks still not being covered either by markets or by government. Changes and reforms are necessary to achieve a more dynamic economy, growing faster, an economy that serves people, and not the other way around. Many of the policies are hardly novel—variants of these policies have worked successfully in other countries.

Even if we get the politics right and succeed in achieving the reforms described here, attaining a middle-class life may still be difficult: even families with reasonable jobs may not be able to have an adequate retirement or afford to send their children to college. Just as, traditionally, farmers helped each other raise a new barn, and just as families pull together in times of need, our society works best when everyone works together. The positive agenda of restoring growth for all is part of the broader ambition of making a middle-class life accessible to all.
