The big one there is food and housing subsidies. The way way we have it set-up can create a situation where a raise can cost you benefits that are worth more than the raise. With disability benefits there can actually be limits on the amount of money you’re allowed to have in general, which means that disabled people can find themselves in places where not only do they need to avoid trying to find work that they might be able to do, since trying and failing can still make them need to restart the benefits application process or even pay back historical benefits, but they also need to reject gifts above a certain value and can’t prepare for any type of emergency, like a car breakdown.

It’s annoying because it creates a disincentive to do the things that would help people on assistance actually get off of it, when the people who push for those limits purport to want them for exactly that reason.
Tapering off benefits as income grows, but at a slower rate than the income growth creates a continuous incentive for a person on benefits to increase their earned income. (If you lose $500 in benefits for every $1000 in income, your $1000 raise still puts $500 extra in your pocket, instead of potentially costing you your entire $8000 food subsidy)

Can’t do that though, because it doesn’t punish people for the audacity of needing help.
