“grow every single year but in a world where like you can also double labor force every single year how fast can the economy grow and i think it could double every single year at the very least would be like tens of percent every single year okay the rate of interest should be pretty close to the growth rate it won't be exactly that because of consumption but it should it should be pretty similar so then we'll go into a world i think in the 2030s where the rate of interest is like tens of percent”
