that's actually something I've changed my mind on over time. Before I became an official commie capitalism-hater, even. Growing up in a small town whose downtown got fucked by Wal-Mart, I get it. If I have to choose, I'd rather shop at a small local business.
But then I met Spouse. They chose to work for corporate Starbucks over a local cafe or restaurant because they could be reasonably certain that their SB coworkers wouldn't call them homophobic or racist slurs and if they did, they'd get fired.
Small businesses have the same power dynamics that make big corpos evil. Interpersonal relationships CAN render these power imbalances less toxic, but they can also render bigotry even more powerful.
