For a kindergarten teacher, they get to spend the whole day with children. That's horrible for some people and beautiful for others. You get hugged a lot, if you need that in your life, it's unthinkable doing a different job.
I can't get to do anything physical in the morning (walking kids to school is a lot of effort for me), but my brain goes full power in front of a pc in the morning, so it's great to have WFH privileges.
Different jobs have different requirements. This is also why I don't have to wear a respirator to be fair to workers at a chemical plant or move around heavy boxes to be fair to warehouse workers.
The fact that my job has different requirements doesn't make it "more important". Just a different job that needs different things.
You can't argue our jobs are more important when theirs are just the same, if not more.
As with out them you wouldn't have your conveniences, food.. We are a very entitled bunch.
