What will we do? Go 50 miles in ANY direction and you will be in the middle of fucking nowehere buy property, when you get old you can sell it and retire.

There is no such thing as over crowding or over population except in Tokyo. I live in the suburbs of Los Angeles and if I take the I10 (main east/west artery in SoCal) east for 20 miles I am in the middle of nowhere. If I take the I5 (again, major north/south artery in SoCal) more then 30 miles, I am in the middle of nowhere and this is Los Angeles, not Iowa, Montana, Nebreska, Idaho, Dakotas, Colorado, etc.

The population could explode by 20 in the next 100 years and we still wouldn't run out of space.

More housing = more jobs = more stores = more everything.
