Could you please elaborate? I don't exactly follow. Nobody is forcing them to work for Uber. If what you mean is they have bills to pay, etc, it's not like Uber can just magically decide to pay $9/hr, they will likely need to cut most of the jobs at that point anyway.
According to the article people who want to deliver have at least two choices and one pays significantly more than the other because Uber doesn't have enough volume right now and the volume they do have tends to go to people who have been delivering for some time.
The article says that with Foodora you can make more money starting out, but they schedule when you work. With Uber you just work whenever you want. People trying to decide which service they want to work for are going to use those factors to make a decision. I think it is hard to claim it is exploitative when people clearly have a choice where they work. Keep in mind Sweden doesn't have particularly high unemployment either, so there are a lot of other options out there in addition to these two.
No, but a proposition like that doesn't address the details.
Reading through this thread its clear that Sweden doesn't have minimum wage; they have strong unions instead (FWIW, I don't see how those are mutually exclusive). Problem is that unions are circumvented partly or completely by freelance constructions like the one we're discussing (another example would be MLM constructions). That needs to be addressed, by law enforcement or lawmakers (politicians). In order to achieve that, publicity like this may aid that goal.
