I'm not familiar with Columbia or Charleston and thus can't comment on their local issues. I just am constantly hearing "growth for growth's sake is a good thing" around Greenville and just think that continuing rapid population growth (and accompanying sprawl) isn't necessarily a good thing. There are plenty of cities in the US with low population growth that have other good qualities, such as high and increasing income levels, that lead to high quality of life. Having lived in Atlanta, NYC and elsewhere, I just think that people in GSA should realize that smaller cities have a lot of benefits and that not every city should be trying to chase a larger population.
