I think you've phrased it rather goadily because it sounds like you're blaming the working poor.
To put it another way, you could say that people in more deprived circumstances are bearing the brunt of covid's impact, and are also among the least able to be able to mitigate its effects.
Data shows that people on lower incomes are three times less likely to isolate if they get symptoms, or a positive test.
But this isn't because they are 'stupid', as some posters seem to be implying. (Or yelling while foaming at the mouth, in some instances.)
It's because their economic and social support circumstances are so reduced, or even non-existent, compared to wealthier people that they simply have no option but to carry on.
The data also shows that intention and motivation to follow guidelines are laws remains universally high across all socio-economic groups.
So basically, lower-income and deprived people want to do the right thing as much as everyone else. They just can't afford to, in many cases.
Quoted from a recent BMJ blog article which covers all this:
Unlike hand-hygiene and social distancing, self-isolation requires support from others to be possible. This includes support from others in the community, in the form of shopping most obviously. It also requires material support in the form of an income and sufficient space. The lower adherence rates for self-isolation therefore suggest that the issues may have less to do with psychological motivation than with the availability of resources. This accords with data from the first “lockdown” showing that the most deprived were six times more likely to leave home and three times less likely to self-isolate, but that they had the same motivation as the most affluent to do so. Non-adherence was a matter of practicality, not psychology.
