The analogy is spot on. Since your a Brit I'll forgive your ignorance in not knowing that the Pilgrims tried your socialism when they 1st left your monarchy.Here is snippet of what happened:
For the young men that were able and fit for labor and service did repine that they should spend their time and strength to work for other men’s wives and children, without recompense. The strong, or men of parts, had no more division of food, clothes, etc. then he that was weak and not able to do a quarter the other could; this was thought injustice. The aged and graver men to be ranked and equalized in labor, and food, clothes, etc. with the meaner and younger sort, thought it some indignant and disrespect unto them. And for men’s wives to be commanded to do service for other men, as dressing their meat, washing their clothes, etc. they deemed it a kind of slavery, neither could husbands brook it. The experience that was had in this common course and condition, tried sundry years, and that amongst the Godly and sober men, may well convince of the vanity and conceit of Plato’s and other ancients; — that the taking away of property, and bringing into a common wealth, would make them happy and flourishing; as if they were wiser than God. For this community (so far as it was) was found to breed confusion and discontent, and retard much employment that would have been to their benefit and comfort.
Why are you unable to grasp this basic fact of human nature? Man is corrupt and corruptable. There has been only 2 PROVEN forces in all human history to counter this corruption. COMPETITION and A BELIEF IN, AND ACCOUNTABILITY TO, GOD.
You, like most of the left of the world believe in neither. THIS is why your belief system is the enemy of humanity.
