Governemt spending deceases the amount that private people have to spend. So if the government is spending money that results in cars being purchased its only because they money was taken from someone which results in less cars being purchased.
TAKE and SPEND. There is no free lunch or positive economic multiplier from governemt spending.
But, as Williams points out, not all of the money through government spending is raised through taxation. We’re running a big deficit.
Obama’s trillion dollar spending spree was graft money that did not benefit the economy. Trump’s infrastructure trillion dollar proposal will leverage local and private spending, create tens of thousands of jobs and boost the private sector.
