My issue with the meme is that it says socialism WILL do XYZ instead of socialism HAS (although "will" is likely reference to western societies but digress)
It is already scientifically proven that socialist societies have better nutritional intake, life expectancy, real wages, education, healthcare, social mobility, leisure time, real wages/purchasing power, tech research, equality among sexes/races/nationalities, ratio of green land, and even seemingly unrelated things like better interpersonal relationships and sex, when compared to capitalist peer nations.
Most famous example: USSR. If you compare every metric you would use to define "quality of life", you will find a SHARP improvement across the board when the tsardom ended and socialism began, and a SHARP decline when it was overthrown in 1991. The same will be found in any socialist society.
How exactly this occurs is a very long answer, but suffice to say, when society is run for the general welfare of society, it tends to perform better for general society than a system whose sole purpose is enriching the rich.
Any sources I can refer to for the USSR claim? In my (limited) knowledge all I can recall as a result of USSR's policies was Holodomor. And Holodomor was probably one of the cruelest genocides in the history of mankind.
Holodomor is Nazi propaganda. There was a famine in that time, it was bad, and the Soviets did their absolute best to address the situation. Notably that was the last famine in the regions comprising the USSR, compared to the tsarist era when famines occurred every few years.
