You are if you are not an opponent of the welfare state and the whole system of "progressive" taxation that funds it according to both Ludwig von Mises and F.A. Hayek. Socialism started out meaning "government ownership of the means of production" with the ostensible purpose being "equality." But the socialists of the world quickly determined that it would be easier to allow (heavily regulated) private enterprise to exist and then plunder it with taxes to fund their utopian dreams.
There is a long tradition of intellectual opposition to all forms of socialism, including welfare statism, in the Austrian School of Economics.

And, sadly, there's been a growing acceptance of many forms of socialism in America for a long time as well. The latest ploys are often sold under the 'all for the kids' caveat.
