If middle class has to have the same effort the previous generation did for the same results, where is the GDP per capita growing for? Doing the same as the previous generation and getting the same means a diminishing rate of income. I agree that our generation consumes a lot more, travels more, goes out to eat more, drinks more, etc. But maybe that is the consequence of not having a home and having high rents, not the other way around. For the past 20 years the RE market has been very unstable for our generation.
