All work requires a degree of skill and time, people just don't respect that at all, have to know what you're doing even at the most deceptively simple 'unskilled job' how to hold a shovel so you don't get hurt or use the OS of a register. It still takes like 6 months for a supposed 'unskilled laborer' to become fully efficient at their position, it may not be the years of a skilled tradesman or similar, but thats something to consider that so few do.

Anyway, is just daily/weekly life in retail or anything public when something goes mildly wrong (even if just in their heads) to an asshole customer. 'This is why I went to college', sweet summer child, if you only knew, or parents warning their kids to go to college so they don't end up like me (LOL). This is a system where you can do everything 'right', have whatever paper qualifications and still end up in a 'low-skilled' job, moreso the more minorities you are. Anyway, more minorities you are and less people believe you, a situation I will always find myself in personally.

Anyway, I don't feel too bad when I hear the phrase since I shadowed a doctor getting told that quite a bit by boomers as part as an internship I had to do, its more about being a classist supremacist asshole than anything else.
