The issue is that they're not treating them as contractors when it benefits Uber, but are treating them as contractors when it benefits Uber.
They need to pick on or the other. If one of those options does not work with the features Uber wants to provide, then they have to make a choice.
We're incentivising companies to squeeze salaries instead of innovating. To me that is the exact opposite of what we should do. If anything, minimum wage should be pushed higher and higher at above inflation, as an incentive to invest in labor saving measures.
There's no reason why we should encourage wasting human capacity by making it easy to exploit people for low wages.
(Yes, this would mean dealing with unemployment by e.g. reducing working time and/or basic income variations or similar)

>>This has nothing to do with price floors.
The quintessential labour standard is a minimum wage, which is a price floor. This has everything to do with price floors. In fact all labour standards can be assigned a monetary value and the combined value can be considered a price-including-benefits floor.
>>you're assuming that workers have a choice regarding where to work. That is simply wrong.
I don't understand. Why do you believe they don't have a choice?
>>So wrong that I understood your comment was a joke.
I'm certain you were trying to mock me.
