If it's only inconveniences like $65 coffee that sets touchy people off enough to storm the Capitol or something, that's definitely not a riot. It's been fully proven by the party in power to be a legitimate demontstration of opinion.
Empathy. If well-off people were to fully understand the situation the rest of us find ourselves in, and the increasing likelihood that it will eventually become a problem for them, too, they'd put all of their HOA-busybody/PTA-pearl-clutcher/campaign donor might behind solving the issue. They are currently in "ignore it, it doesn't effect me, it's not my problem" mode, heavy.
What would it take anyway . . . ?
