I never claimed minimum wage jobs dont need to be done. No one is claiming those jobs should be abolished. The problem is when you have far too many low-skilled people then the laws of supply and demand dictate low-wage, everyone wants to to do it. When you have high skilled people most of them wont want to do low-skilled work, so the demand for doing the work goes down, and thus the pay goes up.
No one is suggesting **everyone** needs to be "upskill", only the people who are capable of it until you drive the wages up enough to not need to "upskill" people further.
No one is suggesting all people need to be coders and plumbers and engineers, just that more people need to be.
