In California in the mid 1970s, two incomes (or more) began to be allowed for mortgages.
This began a big rise in the price of houses and over time ended up making them very difficult for single income families to afford. Immigrant families (illegal as well as legal) were more comfortable with several generations living in one house and would pool multiple incomes to buy houses.
Today in overcrowded, used-to-be America SoCal, old homes can go easily go for $440 a square foot. Prices would be far more reasonable and neighborhoods less crowded if the million or so illegals in SoCal were sent home. I won’t bet on that ever happening.
