Socialism is a font of ideas that simply do not work. Thats putting it mildly. If anything, socialist ideas make things worse. So how does one prop up ideas that are broken and do not work? Simple: they lie. One certainly cannot prop up broken ideas with the truth. So its, lie, lie, and lie some more. The communists did it that way. The nazis did it that way. And the modern day socialists do it that way.
It doesn’t work because it’s contrary to human nature- thus they eventually need FORCE to keep their agenda going.
Just saying, putting socialistic intentions "up front" may well win an election. See, for example, touting how grand "democracy" is, when democracy is one of the identifying features of socialism.
