These days Affordable Housing is a misnomer.
Affordable housing is suppose to be affordable to medium/low income households.
You're right when you wonder if these things mainly pertained to "Boomers"
Because back then, the Affordable Housing index was set at No more than 3 times your income
So all workers could afford to buy a house with very little stress.
Today, Capitalism has made sure that House prices average 8 to 10 times a persons income.
There is no way the Housing index return to Boomer Index.
The Banks/Lenders are making too much money to let it slide.
