Exactly, while others, with the financial resources to do so, live in nicely insulated locations. I am very familiar with the smart growth agenda from 10 years of local experience. They are socialists, and the only ones who agree with their proposals are racists and/or snobs who like the buffer zone around people they don't want to see. Hence the anti-Walmart movement--they don't want low-income types shopping in town.
Exactly wrong again. Smart Growth proponents advocate a MIX of income groups, ages, etc living together in neighborhoods. It is 1960-1970 zoning that segregaged neighborhoods by income and kept all commercial activity out of neighborhoods and made schools huge and far away from neighborhoods, rather than small neighborhood based schools. It prohibited small stores and service businesses such as hair cutters, dry cleaners, drugstores etc. from being inside the neighborhood. It outlawed connected streets between residential neighborhoods in an effort to keep the undesirables out. You've got the wrong people identified as snobs.
Smart Growth advocates a mix of housing types and price, schools, small service businesses, churches, etc. embedded in neighborhoods by design.
You really need to educate yourself about what Smart Growth is about. You don't have a clue.
