Families being squeezed for more money pushes both adults into the workforce. Well if both work they can afford more rent, if they can afford more rent then the house is worth more to a landlord and the price goes up and up. Banks profit, landlords profit. You get fucked.

Even if you buy instead of rent, the banks are making more than ever on the higher interest that result from high housing costs.

Neither of these contribute anything of benefit to society. They don't build roads or improve the local community. Yet they benefit from the work of others who do by increasing the amount they take even more!
