For the life of me, I will never understand why local and state governments never, EVER think to be proactive and do everything they can to build/increase the housing inventory when their state/city is in the early stage of a boom. It perpetually seems like every city in the US that experiences huge growth (Columbus, Austin, Denver, Atlanta, Dallas, Nashville, etc) does not even begin to THINK about about building new housing on a large scale to keep rents and mortgages affordable until it's like 5-10 years too late.
Because there are very strong and influential anti-development forces at work that will always win out until the pressure from rising prices is too great for politicians to stop siding with them.
