No, they got sick, now they have a long lasting condition and can’t work because of it. They did get treatment but can’t be cured (as of today long-covid is still a mystery). They didn’t lose all their money because of the medical bills, they’re losing their money because they can’t work anymore and the state is not giving them “benefits” (horrible word in this case). One is an issue with healthcare, one is an issue with social welfare, again, not the same thing.
Most of the time, the issue is indeed the oven. Sure, you can mess up your dough (or worst, use store bought one) but the culprit is likely not the innocent pizza itself.
