Strict welfare reform. President Obama gutted the welfare reform in 2012.
In the very least get rid of so-called 'welfare cliff' where the benefits go down and you get less when you go over a certain threshold. That means people shun overtime, second jobs, promotions, and salary increases. This is so counterproductive when combined with the rules put in place to restrict what you can buy and also where they go through people's personal items to see if the woman has a boyfriend or someone else supporting them.
