I can't speak to other countries, but in the US it's because the country is aggressively capitalist, and solutions to homelessness would hurt the bottom line for rich people.

Right now investment companies like Blackrock are buying up homes and using them as investment opportunities. This is causing the price of homes to get higher and higher, making it harder and harder for people to afford homes.

In theory this could be fixed by affordable public housing, or regulations preventing buying up large numbers of homes that are being used as rental properties, but the rich folks don't want that, so.
