It is emotionally convenient (esp. for main-stream media) to blame President Trump for everything, but it is typically local city councils, usually Democratic and not Republican, that is responsible for the rent-seeking. The results are housing scarcity, the high costs of housing, renters paying much more they would in an efficient market, and landlords getting far more money than they would get in an efficient market.
Japan fixed this problem by having federal laws that overrode local laws that supported rent-seeking to disallow zoning density restrictions. The results: in 2014, 140,000 housing units built in Tokyo vs 20,000 in NYC and less than 90,000 in all of California.
The lesson: don't blame President Trump. Seek out and destroy rent-seeking market inefficiencies. Let the market do its thing and you'll see far more affordable housing. Japan has already demonstrated this fact.
