Quote from Ed Breen:
GDP is not a measure of a nations 'wealth.' GDP is a tortured measure of spending. It was created by an FDR socialist working at NBER who wanted to conflate the private sector and the government sector in one metric. He himself did not believe it
should be used as a measure of wealth.
Think about what the GDP metric is made up of...C+I+G + net imports/exports.
The first part is consumption....consumption is not wealth. Consumption can only take place by spending surplus production....either present production that is not reinvested, past production that has been 'saved,' or future production by borrowing against future surplus production.
The second part is Investment...this tries to measure how much production is reinvested in maintaining levels of production and creating new production....here we have some measure of wealth creation because assets are being created or maintained in this action.
The third part is Government Spending...well that is almost all consumption so it is based on surplus production, presently, saved or borrowed against the future just like Consumption.
Then there is the net of imports/exports...that isn't measured well and it is not clear what it means in terms of wealth anyway, it certainly does not measure asset investment.
The only part of GDP that can measure anything like wealth of a nation is the investment component.
A better measure of 'wealth' would be to aggregate a nation's assets...but we don't have metrics for that because all of our government produced metrics were created by Keynesian socialists eighty years ago and they did not see the difference between production and consumption.
Consider dividing GDP by I (investment)....how much of a nation's GDP is being reinvested for wealth creation? in the U.S. today we are talking about something like 12% to 14%...in China we are seeing investment of something like 55% of GDP...which country is getting wealthier?
