It sure is damn noble. Someone has to do it, or we all have to. And I give those people amazing props for doing those things.
Many of us have either done those jobs and taken pride, or have family who have in order to better the lives of those children. Saying that work is not noble is demeaning to those who worked for your current standard of living.
The video is about people choosing better opportunities for themselves. If there aren't people to do those hard jobs, then those jobs need to compete with the opportunities these people are choosing instead, for example through higher pay. Saying these people should choose worse work, for the benefit of others (eg. business owners), by appealing to some nebulous concept of nobility is exploitative.
can't get workers to work hard 8 hours a day doing hard labor, maybe add more breaks than the minimum you are legally required to? Or maybe stop suspending the workers next two shifts because they were 5 minutes late from traffic 1 too many times? Maybe consider that threatening to fire workers if they don't work late or overtime isn't productive? Maybe stop paying minimum wage which hasn't risen with inflation or rent prices and increase your prices out to compensate or consider that if baseline worker wages have risen slower than inflation, but management's wages has risen faster than inflation, you've had to do so off the back of your workers ability to have spending money outside of barely living.
