If people are unhappy with the outcome of harmful, irrational policy, they should feel empowered to riot. The government and representation is supposed to work for the people, after all. Accountability is important in governing systems.
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.
Not a lot of domestic coffee production. I'm pretty sure there would be riots in the streets if coffee was $65/lb.
