All “growth” in gdp seems to go to rich people. Normal people have seen stagnant wages and increased costs from the owners. Why should I care if gdp isn’t increasing when I don’t see any gains whether it does or not?
The economy doubling in size helps most people even if the resulting wealth is unevenly distributed. Goods, services, technologies, jobs, etc are good.
Also, extremely uneven economic distributions tend to be bad for large segments of the population due to inherently limited resources like desirable beach front property as well as artificially limited resources like city apartments.
