(To grossly simplify the single-nation macroeconomic picture, at least)
C = consumption
I = investment (the first one)
G = government
Xn = net exports
W = wages paid to labor
I = interest on capital
R = rent on resources and real property
P = profit to entrepreneurs
consumption ~= wages, so if wages go to zero, the economy massively shrinks unless government steps in with something like taxation to fund UBI, sovereign wealth fund distributions, or direct universal ownership.
