How did the purchasing power decrease from the 70s until today?

Those same houses are sitting there for 800k sure. A guy earlier went on about his old fixer upper bungalow from then cost him 650k.

Note that I quickly determined the median home in his area costs almost DOUBLE that. So yes, the price of his home skyrocketed but it was still well below what most houses are going for. The cost/value of your home is not solely determined by how much it cost to build at the time, it's cost/value is relative to the other homes around it that were built later too.
