>in fact the GDP would go up if 10,000 grubhub drivers got replaced by 1 dispatcher and 20,000 robots reaching twice as many customers.
The GDP only goes up if people are spending more money, retard. If you replaced 40% of the labor force with robots, those 40% would now be out of a job. Which means not only would they stop spending money, but they'd be unable to pay their mortgages. The entire housing market would collapse, there would be mass foreclosures. Not only would the banks not be paid back, but they would take massive losses on all of their investments. There would be bank failures a thousand times worse than the 2007/2008 financial crisis.
The only way 40% of the workforce being replaced by robots would increase GDP is if those 40% found other jobs, or if the state intervened to boost demand. As I said, go read some Keynes you retarded nigger.
