Leftism always thrives in an environment of unreality. It dominates Academe, government workers love it, it is always fashionable among the "Hollywood" crowd. In fact, in every segment and micro segment of society where people don't actually work for living, Leftism prevails. Hence, it is very popular among The Young, particularly college students and young adults.
I was fond of many Leftist ideas until I started working to support myself, at which point I saw how much of my money came out in taxes an d began investigating where all that money was going. No more Leftism.
And now, in addition to the natural tendency to wonder why, in such a rich country, some people are suffering (HINT: Because they don't play by the rules), we have probably a majority of our students who were "educated" in public schools, who at the same time were indoctrinated into Leftism.
Seriously, it doesn't look good. Majority rule isn't so attractive when most people are either stupid, inexperienced at life, or compromised (voting their own personal pocket).
We are fucked.
