Just because you don't "see" the work humans currently do doesn't allow you to be ignorant to it happening. Just because you personally don't want to work (as most people) doesn't mean there isn't plenty out there for people to do.
Are housing prices, at least in the U.S. actually attached to the value of work, or they mostly affected by the banks willingness to hand out money?
Let's go another step and take work out of it completely. If houses were free, there would still be houses that are worth far more than others, simply because of proximity to other things of human interest.
That "a median house still costs 4x yearly median salary" means exactly nothing. The size of median salary is market driven, and the price of housing reflects the games banks and housing developers are playing, and thus can be arbitrarily high.
When people only think short-term (what's can I afford monthly) vs. long-term (what will I pay out over the life of the loan vs. what I'm getting now) they make mistakes. These mistakes are self-inflicted but these people tend to then blame any and all others for why they can't get ahead, why the system doesn't work, why the American dream is dead :).
The situation is different from the TVs and computers and cars because those are not considered as important as your own house. Most people eventually have to move out, so they have to participate in the game. I believe we call it "inelastic demand".
I'm on board with surfing all day while you maintain the robots to make my food. Is that cool with you?
What is an example of a non-government bullshit job?
