This would be partially explained by: https://en.wikipedia.org/wiki/Velocity_of_money

I don't completely understand it either though, say you cut one blade of my grass and I pay you $20, then I cut one blade of your grass and you pay me $20, rinse repeat and you get massive GDP, but no increase in wealth. Now do something similar with housing, except this time print a whole bunch of money and pour it all into housing (including construction), and compare that to a country that instead invests into education and building manufacturing plants - who is going to be wealthier?

I think this is all far more complicated than governments let on, or maybe they actually don't even understand it all, from what I can tell a large number of economists don't, so perhaps it's no surprise we're in the situations we are.
