credit card usage

[Abiezer]

Credit card companies set up with the low profits from those of us who pay off our balances every month to obtain the high profits from those who use credit to buy things, usually prompted by marketing, that they don't have the money for. These latter folks often have a poor understanding of the cost of credit and finance in general.
I enjoy the prize dollars on the backs of those who pay the exorbitant late and interest fees the CC companies would not be able to pay the points that they pay to me without the income from the other people.
