I spent two weeks delivering for Uber Eats and made $4.40 per hour

Time and time again, Uber has shown that undercutting their competitors in pricing is not done through smart technology or better business models, but by avoiding regulations and getting away with inhumane wages.

The alternative for many unskilled people would be to be unemployed and having even less income, would that be more or less inhumane?

This is essentially an argument against having a minimum wage in general (and more broadly, certain labor regulations). It's a complex issue that we could argue about for pages and pages of comments, but suffice to say the vast majority of the population in the US, let alone Sweden, disagree with you.

Which is that in some cases it is better to have some unemployed people and some (ideally a lot more) people earning a good wage, versus both groups earning a crappy wage. Combined with a welfare system.

And most economists agree with the grandfather comment..

Not at all, no. Throughout the world, unemployment is correlated with the local minimum wage - as the minimum wage increases, unemployment decreases. Somalia (no minimum wage) has an unemployment rate of over 60%. Increasing the minimum wage in US states produces no negative employment effects.

There are, of course, paid professional conservative economists who will tell you whatever their bosses want them to in support of pro-billionaire economic policies.
