Yes, the current system ABSOLUTELY encourages someone to be a slave to the system.
The reason is simple: People can be better off financially if they use the system than they would be to get many lower level jobs (which are often the only ones they could get anyway through a combination of personal matters and the present economy).
The government also needs to close some major loopholes, such as income-based housing that doesn't county child support as income.
For example, there is a woman who lives in such a housing community near my mother's house who brags to everyone about how she gets over $5,000 every month in child support for her three children and none of it counts as income.
Since she has zero income that is counted, the government pays her entire rent and utility bills because it considers her to "need" those things paid. Since she has no rent or utility bills to pay and over $5,000 coming in every month, she hires a nanny to watch her three children while she goes out and parties on the child support money, then tells everyone all about it.
The worst part? She tells young women her "secret" and advises them to do it: "Just **** a rich guy and make sure you get pregnant and wait for the money to roll in." Apparently it was all done on purpose.
Yes, this is an extreme situation, but I have no doubt it's not the only one like this.
