But that's not 20m in R&D ... its all "creative, professional and knowledge" sectors. People employed part time at $18 per contact hour to teach students conned into going into debt on their student loans to pump up the profitability of private two year business colleges are part of that 20m, for instance.

Look at the growth in employment in "creative, professional and knowledge" sectors in the US from 1945 to 1960, as a percentage of the workforce, and the comparison will not seem nearly as dramatic as 21,000 in 11 years versus 20m in 25 years.
 

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
