However much we like to complain about prices in San Diego (or California in general), we have it pretty good compared to other places in the world (wages to housing prices wise).
In poor countries, it’s very common for houses to cost $100k to $1M but the average salary to be only $200/month. Eastern Europe is the most horrible place to live if you’re poor. The freezing winter cold kills thousands of people per year. Better to live in a shack in tropical Thailand where the weather is warm and you can grow your own food.
