Vicious circle with high demand

services like Airbnb, Amazon Mechanical Turk, Lyft, and Uber, which classified workers as independent contractors and thus avoided paying for worker benefits and employment taxes.
On the last point there are clear advantages for companies to operate this way and on the face of it, it seems very much in their favour. But then go to the first point. If there were only a handful of people doing this you might question their sanity. 28 million is a reasonable number even in a geographical context such as Europe. Some of these people are no doubt already in some form of employment but choose to do things on the side for extra money, for obvious reasons.
All of those roles listed - and many others - are in high demand due to the number of people who use such services.
There is demand for all aspects of this (including from the companies that want such workers) which is why I don't think it'll just go away very easily. Sick pay, bare minimum pension contributions etc that you get from being "properly" employed aren't all that good in any event. In which case a better solution would be that being employed is so much better that this becomes unthinkable. But that will never happen. There is always demand for this type of arrangement from all sides: companies, workers and consumers.
