I think this will be one of the better things to come out of COVID, this "i have to go to work no matter how sick I am" mentality seems to have been done away it....for the better.
I have to disagree with your understanding of human nature, especially in the workplace.
First of all let's agree that "no matter how sick I am" is hyperbole. Perfectly acceptable among intelligent folk, but some of your ideological siblings don't understand the concept at all.
I could be hyperbolic and say that the mentality of many is "if I have little sniffle, I want to sit on my ass at home for ten days and still get paid. Ka-choo, and ka-CHING!"
Let's avoid hyperbole and say that people like think "Even if I'm not feeling so good, people are counting on me for their own jobs. So unless I'm contagious with something serious that will make other people miss work, I'm going in to get 'er done." Let's say other folk think 'I have plenty of sick days owed to me, and if I wake up not a hundred percent, that is a good time to use them. No one ever died thinking, "I wish I had worked more."'
That's how different people used to feel pre-COVID. Guess what? That is how they still feel now. People haven't changed. Those who are dedicated to our work are still dedicated, and those who believe a job is a burden and that their employer owes them more than the day's pay they signed for still have that attitude.
The only difference is that the second type of person had a couple of years in which their philosophy was given free reign, especially once the Democrats realized that we could get COVID over and over, no matter many times we got vaccinated.
At a point coming very soon - like January - the representatives of the participants in the Great Resignation will lose seats, and two years later, the White House. Then the country will get back to rewarding hard work, Blacks will have the lowest unemployment rate in history - as under Trump - and the dollar will stop losing value like a Tesla with burned out batteries.
