There's another issue though: people on disability payments often have disabilities that prevent them from working full-time. So in order for them to climb over the financial cliff they've got to find a part-time job that pays a lot more than what they receive from the government. That's a much more difficult obstacle and it keeps people from otherwise taking a low-paying, non-physically-taxing part-time job to earn a bit of extra income. It makes no economic sense.
