I've noticed something.
People who often call other lazy, ungrateful or tell them to accept any job they get (no matter how bad it is) are almost always in higher paying positions, typically middle class at least and white collar worker.
I once discussed it here on reddit, saying I didn't want to work a low wage job, specifically factory, for the rest of my life. Some commenters were supportive and helpful, offering me advice, yet others were calling me lazy and ungrateful.
Once I checked their post history, those commenters ended up all being in high paying jobs, with degrees and jobs that pay high salaries, and after asking them none of them actually worked in a factory before. None of them actually worked manual jobs, none of them worked in a factory or did hard work for a long amount of time, yet they still had the audacity to call someone who did these jobs lazy.
I told them I would be willing to do it for the short term and they kept insinting that I should do it for the rest of my life.
There is something seriously wrong going on with these people. There's definetely a good percentage of the population trying to push other people towards the bottom.
