Because there are only a small portion of jobs that can effectively be done remotely. A few long-term trends I see driving the move to big cities are: 1. Jobs are becoming more specialized, and so it's more difficult to find every specialty you need for many businesses in a smaller town. 2. There are many more two earner households. In the past, many people would conduct a job search over a wide area and move the family for the man's new job. If the woman already has a job she likes, especially one that would be hard to replace in another town, the couple is much less likely to move for a job opportunity. 3. Businesses know this and have noticed that it has become harder to recruit people to move to a smaller "company town" for an opportunity. They therefore have tended to locate new operations in bigger cities.
