I love how he repeatedly throws out the 1.5 quadrillion figure out there when cars cost a fraction of what they cost now in the 70s and the average income was much much lower then. Inflation at work. An intelligent person would instead compare cost of living percentages, quality of life (no bread lines now are there? No masses of drifters moving from city to city looking for work?), and % of unemployment. 1.5 quadrillion world wide is not a big deal when even whopper floppers make 5 figures annually. In America alone there are roughly 200 million workers nationwide
So lets say for the sake of this illustration they all make 20000 per year
200,000,000 * 20,000 = 4,000,000,000,000
That's 4 trillion, by itself, before you take into account any variables like uber rich, business owners, and the like. One country, just one. We aren't even the top overall country when it comes to earnings. We are around 9th last I heard...
Multiply in all the other places that pull down that earning power (Japan, UK, France, Netherlands, Australia, etc) And that 1.5 quadrillion number is put into perspective
There's your numbers, but any high school level economics student could have told you that
