Is Social Security socialism?
There is a socialistic component to it.
But it is not socialism according to the more common definition.
And what is that more common definition?
This is pretty close (from what I know)
Socialism - Wikipedia, the free encyclopedia
Socialism is a social and economic system characterised by
social ownership and/or social control
[1] of the
means of production and co-operative management of the economy,
[2][3] as well as a political theory and movement that aims at the establishment of such a system.
[4][5] "Social ownership" may refer to
cooperative enterprises,
common ownership,
state ownership (achieved by
nationalization), citizen ownership of equity, or any combination of these.
the next sentence does make this pronouncement:
There are many varieties of socialism and there is no single definition encapsulating all of them.
Which means what I call "common" really may only mean it is what I am used to.
Can't say.
