Now do you
1. Kick her out of the car because she's clearly violating the law that you support
2.Keep going with it knowing the you've violated your own principles
3.other-please explain to me
Obviously this sort of interaction would fall outside the purview of government regulation, and in fact given your description of her reasons for offering me the discount, outside the realm of pure commerce itself (doubtful, but possible).
I do not consider 'principle' to have anything to do with any of these issues, but rather interests and political power. As an individual of course I would take what I could get, whether it be a freebie or a discount, but clearly such discounts are unlikely even in the current system, and would be even less so if the woman could make $15/hour at any job.
Regulation cannot necessarily penetrate into every aspect of economic interaction, Milk, nor do I think it is worth the effort to try to make it so. We can rely upon the effect of regulation upon the market in general to correct problems within areas of the market not directly regulated. For example, the union movement historically had an enormous effect of increasing the wages of non-union workers. While typically workers in 'skilled trades' in larger urban areas were unionized, in many cases their fellows doing the same jobs in the areas of suburban growth in nearby rural and small town areas were not. Still, those workers were paid much more than they would otherwise be, due to the 'pull' of the main urban labour market. Contractors in these far-flung areas had to pay their non-union workers nearly as much as they would have to pay unionized ones, in order to prevent them moving on to the jobs in the city.
