Hamburgers are a small part of consumption. GDP is made up of not just C but also I+G . The price deflators for G may be elusive. China does have relatively large I+G. Can you compare price trends? For instance US spends only modest amounts toprotect public health. The rate of return on preventing contagion is extremely high.

This shows how relevant such spending is:

But China spends proportionately much, much less on the public good of disease prevention and control. How does this enter the PPP calculations, prof. Basu? Should the GDP be adjusted for the expected value of unprevented disease epidemics - surely a major contingent liability.
