America's housing crisis has changed the tune of how people perceive affordable housing,  according to a new survey. The poll of 1,000 U.S. adults found more than half believe what they pay monthly for their home is more than it should be — the average person stating they spend 42% of their annual income on housing-related costs. More than four in 10 (42%) parents polled in the survey said they either don't believe or "aren't sure" their children would be able to afford living in the same neighborhood they grew up in, due to climbing housing costs.
