I don't think homeless people need to commute!
As for homes, my 3 bed house (poured concrete) cost $20k to construct, not sure why a mobile 1/2 it's size would cost more.
But if you look on temu, China is building them very cheap.
Just looked on Google maps, north of SF all emply land.
One of the problems about forums, people that know nothing about anything can post any stuff they like and appear to be reasonably intelligent.
Then they out themselves by not knowing McDonald's sells franchises and rents property to make money. Now we have another one that thinks the cost of a home is related to the labour and materials, but in reality it's all about government policy, and easily confirmed by just looking around you in Thailand. No planning policy, so no corruption required to build even though they use real materials, and not pine and sheet like in the USA.
