You see it that way, but the Dutch law doesn't. If the freelancer has no real choice and cannot dictate his/her own terms they are not a freelancer but an employee without the benefits of an employee. Social programs should be displayed these days on your paycheck if you are an employee. Not every (administration) company is doing it properly though.
Forcing freelancers to work more hours for less than a sustainable minimum pay solves nothing as the minimum wage is calculated on a full workweek.
I'm sure Uber is allowed to offer freelance work, but not with the current way of doing business. As soon as they let the freelancer dictate the pay (or at least properly negotiate) it looks they will be fine.
So you might pay a 10% social security tax, and the employer might be paying an additional 15% that doesn't appear on your payslip.
That's what Amazon, etc. are talking about when they say they pay a load of employment taxes.
That's also why a lot of countries are eying the gig economy with skepticism, it's actually often just a massive tax dodge for the company to not pay employment taxes.
What country is that? US, the only country that its politicians actively lobbies against universal healthcare, healthcare that is successfully implemented in every! f*ing! other! Western country?!! (and quite a few other countries that are not Western, such as my full of corruption Eastern Europe one)
This assumes the meaning of freelancers is being able to join and leave an employer when you want, and not being able to fix your own prices and refuse gigs like others are saying. I think you should be able to open a freelance provider with restrictions, as Uber is doing. I see no reason to outlaw that.
