It’s an ouroboros. The ultra wealthy finance state actors till they become rich (insider trading,etc), then they enter the private sector and become even more filthy rich by getting executive jobs or board seats to lobby the next state actor they can corrupt. I always follow the money, because there are very few true believers actually in power.
Billionaires are pouring infinite money into right wing movements. They have no scruples and can pay anyone they need to get what they want done. The problem is capitalism because it creates extreme unelected power in an extremely small self interested minority. They also fund the power centers of the left to keep things from moving too far against them. Elections move on money far too much. In the end, you can’t have democracy and capitalism. Slowly capitalism always tries to swallow democracy.
Credit cards are a trillion dollar industry. Fraud is already a massive issue and it’s only grew. More and more places are going cashless for easier accounting and lower incidence of local theft. I highly doubt it’s going anywhere. It will become more of a hassle for consumers though - no doubt.
