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.

So how come the studies find that by introducing minimum wage no jobs were lost, it just increased prices by a very small amount?

A 2004 study of available literature, “The Effect of Minimum Wage on Prices,” analyzed a wide variety of research on the impact of changes in the minimum wage. The paper, from the University of Leicester, found that firms tend to respond to minimum wage increases not by reducing production or employment, but by raising prices. Overall, price increases are modest: For example, a 10 percent increase in the minimum wage would increase food prices by no more than 4 percent and overall prices by no more than 0.4 percent, significantly less than the minimum-wage increase.

In a 2010 study published in Review of Economics and Statistics, scholars Arindrajit Dube, T. William Lester and Michael Reich also looked at low-wage sectors in states that raised the minimum wage and compared them with those in bordering areas where there were no mandated wage changes. They found “strong earnings effects and no employment effects of minimum-wage increases.”

A 2012 paper published in the Journal of Public Economics, “Optimal Minimum Wage Policy in Competitive Labor Markets,” furnishes a theoretical model that lends some support to the empirical insights of Krueger/Card. The paper, from David Lee at Princeton and Emmanuel Saez at UC-Berkeley, concludes: “The minimum wage is a useful tool if the government values redistribution toward low wage workers, and this remains true in the presence of optimal nonlinear taxes/transfers.” However, under certain labor market conditions, it may be better for the government to subsidize low-wage workers and keep the minimum wage relatively low.

You can find just as many studies that say the opposite

Regardless, there are two possible outcomes from minimum wage:

(1) inflation

(2) unemployment

Your cited articles support the former; others think it will be the latter. In either case, I doubt the market manipulation helps overall.
