It was very interesting to me where I finally understood how banks (and the overall system) create money. As a bank you start with 0 money, you lend 100 to some person that you "deposit" into their account at your bank. So now on your books you have 100 in liabilities (the money that the person has in your account) and 100 in assets (the money the person owes you). So accounting is balanced. You did not need money to start with, as a bank you just "lend it into existence".
I'd hardly call that controlling the government.
People using it to gamble has more to do with gambling people than with capitalism people. You can have gambling in communism or socialism, only stakes there are limited because the fruit of the labor of people doesn't belong to them like in capitalism.
The capitalism you grew up with is dead, the arguments for and against it are old and stale. That nature of what it is has changed. It's metastasized, devolved into something else entirely as the middle class is evaporating, the lower class is continually squeezed, billionaires become trillionaires, people are lighting warehouses on fire citing low wages as the proximal cause, and the President is ordering automatic SS registration as he threatens total civilization destruction.
This shit is not working and it's only going to get worse.
Gambling, likewise, is a moral problem. It should be illegal or highly restricted and often was. Many other problems we face now could be fixed simply by reinstating laws that used to exist.
