Nutella riots show that even the French can go nuts over a bargain
Well, yes. It’s one of the core observations of economics. Human beings like to get more for less.
From which we can derive two fairly important results.
1) Economic systems which do not have this observation as a core part of the structure aren’t going to work very well. Trying to insist that people will get less for more won’t work. We should pay farmers more for food because farmers doesn’t, for example. Quadruple (an actual demand being made) the wages in those garment sheds in Bangladesh and everyone will be happy to pay the resultant price increase in Zara doesn’t.
2) Economic systems which do cater to this human desire seem to work rather well. One thing we can absolutely say about this capitalism/free market mix is that it makes things cheap. It caters to this handing over less to gain more.
Yes, this applies even to the French, concerns about their relationship with homo sapiens sapiens notwithstanding.
