I agree with the author on most points. I think Houston's diversity and low cost of living are what make this a great city. However, I don't agree with his comments on the mass transit system. Granted, some people feel we need mass transit to make this a "world class city", and that's not a good reason for building something. But as I see it, one of the biggest problems facing Houston is traffic. People who move out to the suburbs may have the nice yard and friendly neighbors, but they spend two or three hours a day commuting. That lowers the quality of life, and hence the value of living in Houston. Having a vibrant urban core with attractive parks, and a great mass transit system, will not only improve the quality of life for those of us that live here, but it will also make Houston more attractive to businesses and people who might consider moving here.
