Possibly due to social stigma. I don’t know that what I’m describing can be attributed to the safety net itself, but many countries with excellent social safety programs also have a low social tolerance for failure. This is not limited to using social benefits - e.g fail in business and you’re a business failure who will struggle to get any financing ever again.

From a European perspective who made similar experiences: European countries all tend to be hyper neoliberal nowadays (despite Americans warped perspective) they don't want to offer social safety nets for ideological reasons but have to because of past, long since crushed leftist political movements having forced them into existence, making it very difficult to abandon them now by the ruling neoliberals.

The net effect is the more slowly, erosion of social safety nets and making it as painful and unpleasant as possible to use them (as a matter of policy), as well as mass corporate media propaganda against it's recipients. It's a miserable experience by-design.
