Who raises the standard of living? How? With what labor and what incentives?
Entire thread dedicated too that but i summarize it for you.
Who raises the standard of living?
* Mankind
I think you answered the "who" below, which seems to be volunteers and government workers, with money collected through taxation, with "for the greater good/motherland (motherplanet?)" I still don't see how this differs from early 20th century USSR. They also used science and technology to support their agricultural projects, and also simply printed money to pay for it, which on worked because no one was allowed to trade that currency for other currencies.
Before i answer anything more , where did you read in my post "with money collected through taxation".
It looks like you read what you want to read ( or what is filtered with your perception unconsciously ) without actually thinking.
