I keep hearing the positives of Socialism. Should I start worrying ?

I think the time to worry is when people who have power are praising socialism as a good thing.

Well, some people try to convince me with the "benefits" of socialism also. However, I have been a student of World History ever since my early college days. I say those who argue for socialism tend to be very ignorant of World History.

Seeing as socialism was created by elites, and has always been promoted by the elites (and their ignorant pawns), yes, be very worried.
Hearing (rich) celebrities and politicians preaching the virtues of socialism to the masses is pretty much like a farmer preaching the virtues of an all meat diet to his livestock.
