A lot of the 1st part the rose-colored classes of collective and selective nostalgia. Especially, when it comes to the times of our youth. We're all guilty of it so you can excuse it somewhat but to look down on others for doing said jobs because you are an ageist and a lot of the time narrow minded at best and at worse elitest is wrong. For everybody who let's say flipped at 16 or so, so they can have extra money to chill with their friends there are countless others who do it because they have to and for many reasons it was the only job they could find.
Hell, we all know people who are vastly overqualified for whatever job they are doing but for some reason or another couldn't find a job and/or pay that matched their actual skill set and worth. That is why this upsets me because nobody has any right to judge others based on what they have to do to support themselves just because you feel they should have aged out of it. As long as it is not illegal or hurts themselves or others who cares.
