Here's the reality of the matter. For the most part, white people don't want to live near blacks, and therefore land/property in predominately black areas is very cheap in comparison to surrounding areas. Sooner or later, once business starts growing towards black neighborhoods, they drive all the black people out and scoop up that land/property for cheap and making a fortune off of it.
If he 'takes the bag', he's going to have to buy land elsewhere, and with how crowded Austin is, he will spend a lot of that in purchasing expensive land and constructing a new building. There's no guarantee that the new location will draw as much business as the current location. Also, we complain about gentrification, but if we're complicit in it, what are we complaining about? This is going to keep happening anywhere blacks move because of the reasons I mentioned before. The land is cheap where blacks move to and then these companies swoop in decades later and get the blacks out. If no stand is taken, this will keep on happening. They've already got most of the blacks out of Austin.
