It's not just that people are going for "better" jobs to avoid the lowest of low tier schlock jobs. It's that a dedicated chunk of those jobs refuse to hire because the employers are trying to downsize that part of their overall workforce and thus reduce costs. An example of this has been the rail shortage, where despite needing twice as many workers as they actually have in order to keep things from collapsing the rail companies are ignoring the collapse and trying to cut fifty or even hundred car trains down to single man crews.

You also cannot trust the Department Of Labor's official statistics by themselves since there's multiple ways that the U.S. government covers up actual unemployment numbers. For example stay at home parents aren't included in the unemployment statistic even if they worked previous to that situation. People who have been unemployed for more than a year are not included. People on disability but who are in an employable state are not included. Gig workers such as GrubHub drivers are not included. Certain methods of self-employment such as traveling musicians are are not included. They pulled this trick a decade ago and they're doing it again to try and prevent another panic. The one difference this time is that instead of people losing a single full-time job like they did in 2008, many are now working multiple part-times and thus inflating the employment statistic slightly since technically they're never unemployed.

Then there's the gap that happens for employees. If someone has a part-time job and gets scheduled from noon to nine for closing back to back for four days and then gets nothing for the next three days that means they're not getting paid the equivalent of a full-time job despite possibly working just as many if not more hours. When you have lulls like this you need a second part-time job to fill them in, leading to things like ten percent of the current counted national workforce having at least two jobs. But many part-time jobs in retail and services want to monopolize the person's time since scheduling is based on the employer's availability and not the employee's, meaning that sometimes the employee will have to purposely dedicate days of their week to waiting in case either job calls them in. If the person doesn't have a free day and are called in while working one of their two jobs, they may be fired from the other job. When enough places and people have an incongruent schedule like this places run short staffed and the person is still wasting a day or maybe more idle. Then there's the other half of that coin of scheduling abuse, the supposed part-time job that uses that flexible scheduling to transform into a full-time job. I know that Wal-Mart will schedule you for no more than thirty hours a week and will stack your shifts back to back, sometimes with as little as eight hours in-between, just so they have enough leftover hours in your schedule that they can call you back to cover someone without pushing you into full-time or paying overtime. This makes working for Wal-Mart hell because you're rushed and then all but told to be on standby, giving you very little time for things like other jobs, appointments, household chores, and even self care. The end result of being yanked between two part-times or being held hostage by a full-time masquerading as a part-time is that eventually the potential employee gets cynical and stops applying for that kind of work entirely.
