It's down to many things. A quick look through MN any hour of any day and you find:
Never going to wear a mask (they can't make me/they don't work etc)
No longer going to follow the rules
Can't do another lockdown (newsflash, the UK hasn't actually had one yet, and if there is ever a real one, which is policed like in other countries, we will be able to do it because thanks to the fuckwits not following the advice now, we'll have no choice)
You also find, hidden in plain sight, the sheer number of people who had a normal Christmas, or who are going about their daily life as normal right now. Flick through Aibu and you find numerous stories that should never have happened in the UK at this time because people shouldn't have been doing the things they weave into their stories.
It's also down to a shit government wanting to dictate the narrative. "We are advising you" "you shouldn't" "it would probably be better if"
Where are the actual clear rules there?
The politico-bots on here who link to the scaremongering clickbait from morning to night (easy to spot, they drop in a hyperbolic thread title to get you clicking, a link to the Daily Mail - which they accept as total, unadulterated fact, and then they never post again)
I don't see how the working poor can be blamed unless procedures aren't being followed in their workplaces. And if they're working, then presumably they are allowed to.
