Bought a 3 bedroom house for $75k because I work remotely. There are cheap places to live in America, you don't have to fly out of country.
is not an answer to "I want to travel" or "I happen to be born in the 'wrong' country and now I'm not allowed to travel"
Point is, cities could be building a lot more housing, but typically can't because of zoning regulations and NIMBY activism. It's a shame.
The true solution to the housing problem is to remove the laws that are allowing supply constraint in "liveable" areas like NY, CA, MA, etc.
The local government there in charge of housing policy prevents people from adding more liveable legal units to their land. So for example if you wanted to remodel your land to have 2 houses on it instead of one, or to be 4 floors tall with apartments, or to have only a very small energy efficent house on it, the local government will tell you "haha sorry no."
This is a really big problem because land is in finite supply and as a result if you have a very dense area of office buildings with 20,000 workers and only 1,000 houses are in a commutable distance, then you have 19,000+ workers who are either going to be renting illegally, sleeping in their car, commuting 50 miles, or paying through the nose for a house.
I much prefer it out here.
