I went through a bankruptcy in my early 30s, largely because of credit card debt, and then immediately started getting big pay raises. 7 years later, I came out of it with an 800 credit score and a six figure salary and it was an incredible eye opener how much money and kickbacks credit card companies are giving to wealthy people for the privilege of using their card, while I was getting fucked 10 ways to Sunday on interest when I was making 30k a year and struggling to make minimum payments. I worked out the math later and it turned out that even with the bankruptcy I had paid well over the amount I borrowed in interest and had barely put a dent in the principle.
These days I’m regularly getting $100 cash back rewards and free flights or hotel rooms and not paying a penny in interest.
I don’t really get the economic incentive of shoveling money at wealthy people while grinding down lower class people into debt slavery.
