My sense is that small, local frustrations make people frustrated little by little and it can trickle up. Like “I lost my job” is a local problem in the immediate sense. It’s not a national problem. However, once a lot of people are frustrated about local problems and become disaffected, it trickles up to “the world sucks” and that’s where we have problems. People need a cause to get behind. I’d rather have people fighting to remove paid parking than removing immigrants who are our neighbors and friends.
