That certainly doesn't look steady, lol. Large investment firms and banks are buying up a large number of single family housing, making it unaffordable.
Wages do go up, yes, with respect to inflation. They get nowhere close to productivity increases, as exploitation rises.
I am referring to the literal times we live in. Single-family housing units are being gobbled up by large firms, this will not show up on your graph just yet.
The Workers are now recieving even less of the Value they create than before, that's a wild way to justify this.
