Qui prodest?

It is quite apparent why CC companies offer $10k in rewards: they will keep commissions on all transactions.

Anecdote: recently I bought a used car. Initially we agreed on bank transaction, tried several banks, some have low limits so low it would take months to move money. Others wanted transaction fee as high as $200 on 20k transaction.

Gov wants to get rid of cash because of surveillance. Banks and CC companies want to be gatekeepers and tell you what you can and can not do with your money. And to pocket as much fees as possible...
