Long-term economic woes fuel anger
Widespread and long-term economic insecurity fuels anger. You can already see it in the backlash against globalization. Polls show most Americans don't want more trade, which is why the president can't get Congress to ratify any new trade agreements. Many people are also angry about immigration. Some even propose denying citizenship to children born in the United States of parents here illegally. The anger focuses on every major institution. According to polls, the public has a record low opinion of government, and also of big business and Wall Street.
Add Privatopia -- mandatory membership homeowners associations -- to that list. The authority of private HOA government has never been fully accepted and respected compared to traditional muni and county government. HOAs consequently get plenty of anger and disrespect from their constituents. Current socioeconomic conditions will only make them more willing to flip off the HOA.
