I think that if a person qualifies for such programs, they shouldn't worry about accepting assistance -- with one caveat: It's not lawful as a Catholic to vote for Obama, for example -- even if it's clear that you'll "live better" if his policies were implemented.
So you must vote for the responsible candidate, even if your poor family would benefit more by a more socialist-leaning direction from the likes of Obama. You can't choose evil that some small good may come of it.
A family living in this horrible modern world, with its high taxes, expensive healthy food (and cheap subsidized food -- corn, corn syrup, corn-fed beef), messed-up economic system (the dollar has lost over 95% of its value since the Fed was created in 1913) -- it would take hours to list what's "happened" to the world in the last 50 or 100 years -- has to take advantage of whatever "positives" are offered these days, which the architects of this modern system have designed to keep people at the bottom of the pyramid alive, and keep them from revolt and/or despair.
In other words, a poor family living in today's messed-up economy without the benefit of welfare, social security, food stamps, WIC, etc. would be like a man in 2010 saying, "I believe air conditioning makes a man too soft and lazy. People used to live without it, so I can live without it today!" even though he lives in a double-wide trailer -- which didn't exist before air conditioning. The man has the right idea -- A/C DOES make people soft, want to stay indoors, etc. But manufactured homes (for example) have little to no insulation, and have no "natural cooling" features like homes built in 1890 or 1910. Not to pick on manufactured homes -- ALL homes built after 1960 or so have ZERO natural cooling features, unless you count roof insulation. They used to orient homes a certain direction, had overhangs, awnings, large trees in front, high ceilings, strategically placed windows, different building materials -- all of which helped you to live an A/C-free life.
It's hard (to impossible) to live a "hybrid" life, where you choose the WORST of both worlds! Having 1910's social welfare net (non-existent) with 2010's economy (weak dollar, two parents have to work to survive, etc.)
And it's certainly better to homeschool your children than to reject assistance on "principle". The latter could be mere pride -- the former actually affects your childrens' souls for eternity.
Likewise, it's much better to have a large family than to reject assistance.
I think we Catholics have to be "wise as serpents" to survive in this wicked age. God's will is still very clear in most areas -- support your family, raise and educate your children, protect their souls, accept the children God sends, etc.
There are PLENTY of things we can't control at all -- so we have to do everything we CAN to live a good Catholic life, within the bounds of morality (no stealing or cheating, for example).
P.S.
Social security should not even be considered "assistance", because we've all paid into it, and most of us will never see a penny of it (unless you're already drawing on it). If you can find a way to draw some money out of that system, DO IT! Don't plan on getting more later -- it won't be there, period.
If you can retire early at 59 1/2 and get 10% of your normal benefits, DO IT and count yourself lucky. If I could "retire" at 35 and receive 1/2 of 1% of my normal benefit amount, I'd do it in a heartbeat.
