This has to do more with price of house, not HOAs. In Florida for example, some(maybe most?) counties require all new developments to maintain their own roads, which requires something akin to a CDD/HOA. Newer houses typically cost more and bring in people with money, not someone who inherited the house or has been living there for generations.

I could show you HOA neighborhoods that look like a warzone, and beautiful nonHOA areas of million dollar houses.

The fact that the government has washed their hands of dealing with pesky problems like maintaining streets is bizzarre to me. How far is too far with privatization?
