But by gaming the system a person can do pretty well. A single mother with two kids making $29,000/year receives net income and benefits of over $57,000. Earning more income actually results in a net decrease in total income+benefits -- this is the "welfare cliff [aei-ideas.org]".
Make no mistake, this is by design. The politicians who designed it and refuse to change it benefit, because the recipients overwhelmingly tend to vote for those who promise more of the same (that's the carrot). When a family comes to depend on these benefits and wouldn't be able to make ends meet without them, they fear the possibility that they might be taken away (that's the stick).
With dependency comes power. You can be absolutely certain of one thing: politicians understand this. They have every incentive to keep people in the system.
I really wish the "mechanics" of power were universally taught in the public schools, along with propaganda techniques, particularly the myriad ways you can mislead someone by carefully crafting your message, all without ever making a single false statement. Framing, cherry-picking your facts, characterization, emotional appeals, bandwagon appeals, just to name a few, should be universally taught and understood. Of course, this is unrealistic. The government funds and operates those schools, and there is no way the government is going to sponsor that. It would be like asking Microsoft to recommend OSX.
