Guess there is much more money in printing what people WANT TO HEAR as opposed to what people SHOULD HEAR. Modifying reality is what radical leftists do...the alternate universe seems to be much more appealing to them.
A separate group, the radical environmentalists that coalesced in the 1960's decried economic growth because, in their view, it negatively impacted the environment.
After it was clearly shown that socialism would lead to an inferior standard of living, the two groups allied themselves. The Marxists got a justification for lower economic expectations, and the environmentalists got the required authoritarian government that was necessary to implement their policies.
No matter how you slice it, freedom loses.
