Gov't Assistance Incentive

Concerning Gov't assistance programs (e.i. welfare, section-8, wic, etc.), individuals either 'qualify' or not-qualify. Thus, there is no incentive for an individual to improve their situation. If they get a job that is a "little" better, they can lose all of their benefits. My proposal is to create a skale that would decrease their benefits as their financial situation improves. If not a skale, at least a point where the beneficiary receives half of the benefits.
