Looking at a list of gold prices one day, where it showed something like, for example, they sold gold for $280 but they buy the same gold for $250. I know they have to make a profit, but I wondered if there was any justifiable reason for this, other than "we have to make money"?
The same thing with car dealers. When you go buy a car, they'll tell you "it's worth $20k, so we'll sell it to you for $20k". But if you buy it and try to sell it back to them a day later, it's suddenly "nah, this is only worth $15k, we'll take it off you for $15k".
Is the 'fairness' argument completely off limits in capitalistic situations like these?
