Agreed, I even saw a “full stack” role that required the person to do testing with a 65k salary
People with better options (most people with the skills to do it...) won't take those jobs.
But as someone from a "non standard" background (no qualifications on paper but could do the job), low paid jobs demanding relatively high skills were actually really useful for me in terms of building work experience and a network.
The environments tended to be chaotic and high turnover but proved to be a useful stepping stone rather than a dead end.
