LOL Like I said, believe whatever makes you sleep better at night. The entire US federal budget in 1960 in 2005$ was about $150 billion - including SS, military etc. Today its nearly $3.5T. Go back 100 years before 1960 and we spent around $1 billion in 2005 at the federal level in TOTAL. There is no historical evidence to support significant levels of pork, investment, etc from the government until the last 60 years, and the results have been dismal with real GDP growth massively lagging pre-ramp of Government “investments.”
I repeat...willful ignorance is no virtue. The policy of government investment is there from virtually the beginning of the US government, of which I have pointed out several concrete examples.
What HAS been a massive failure has been spending on social welfare, which has expanded hugely, and which accounts for pretty much all the massive growth in federal spending. The tiny amount spent for the activities the constitute investments aren't even a blip in that.
