Welfare is defined by the liberal as share-the-wealth and by the conservative as soak-the-rich

Welfare is a public safety net strung up in the 1960s to catch the casualties of the free market system and keep them tangled in the webbing for generations.
Welfare is an example of a race-coded policy, a policy which is has little to do with race but which implicitly evokes racial imagery and attitudes in order to stimulate opposition or support.
Welfare is such that the social safety net should be people helping people rather than government helping people since only 30 cents out of every earmarked tax dollar makes it down to the intended beneficiary while that number is 90-95 cents out of a dollar when it is generously given to United Way or the Salvation Army.

Welfare is problematic in that when you start paying people to be poor, you wind up with an awful lot of poor people.
Welfare is problematic on the grounds that the safety net should not be used as a hammock.
Welfare is problematic in that just as if you subsidize apples, you get more apples, so too with unemployment. If you subsidize it, you get more of it.
Welfare is not a loving act, for the love is not felt when a state administrator stuffs a welfare check into an outgoing mail.
