Incomes are up, but the expenses are up as well, especially with the upcoming changes in healthcare for people on the ACA.

Also any comparison of wage growth vs corporate profit growth over the last 30 years shows that wages have not kept pace with the increase in productivity.

So incomes are only just barely keeping up, when they should be booming.

How can inflation adjusted income be up and there still be an affordability crisis?

Yet more and more people are struggling to afford even basic necessities and one can only dream of the luxury of the 50's when a single working class person was able to pay and cover for housing, car, family and even have enough for leisure. Where has all the economic surplus gone? Right...to the bourgeois, the capital owning class that exceedingly extract more and more of the wealth generated by the society.

because the developing world is producing a lot of things except the housing.
