Fine- but this model (I believe) will lead to higher prices for consumers overall which would lead to less demand and therefore less jobs. This was how Uber was able to beat the Black Cabs.
Additionally such a model (along with zero hour contracts) are flexible which is valued by certain workers.
It’s also problematic with the libertarian fondness for immigration as the swedes are discovering as newcomers find it hard to enter the workforce with collective bargaining arrangements.
Now it may be that in a just society it is right that workers rights and wages should come before customer value/ affordability but this moral society won’t come about through government diktat.
This just society seems to work better through s communitarian franewirknwhich requires a more homogenous and traditional society which would be generally hostile to libertarianism. To coin a phrase it sounds like National-Mutualism!
