Affordable housing is disappearing for the middle class. Growing up, I was taught that you should not pay more than 1/3 of you income on housing. I've heard that previous generations were told that number should be as low as 1/4, 1/6, or even 1/10. Yet some people are paying over half of their income just for a roof over their heads because housing costs are out of control. Something MUST be done about this crisis.
