How is this possible in USA?

Decades of deregulation. More to come.

You clearly do not know a single real thing about America. America itself is a con job from to back, to to bottom, left to right. Between the reserve currency global fraud, the inflation money printing, the scam startups, the deficit spending and national debt fraud, the various banking and financial frauds, even our children are raised with fraudulent schemes with things like the “fundraising” through selling Girl Scout cookies and circulate bars. All the scamming online, in our professional lives, personal lives, or fake religious groups and political entities, is all just snake oil heritage and the rich plundering the country through a fraud based economy.

It’s something that most Europeans that come to America either are shocked by or fall prey to, because not only are laws tighter in Europe regarding fraudulent activities, but in many places of Western Europe, society is still relatively high trust and of good morals and ethics with little of the overt and blatant open scamming and lies you see in America on a daily basis to such a degree that most Americans cannot even see it.

A more apparent example of that is our stores in America that are always having a BIG BIG SALE of up to 80% OFF. When it’s just the same market prices claiming to be 80% discounted from some made up price.

You mean how could someone possibly send their life savings into some bullshit lotto-ticket-account app? Especially when their interest rate is 20bps more than any real bank.

I don't think it's any different from people learning life lessons from all the crypto 10% weekly return schemes.

Read "A decade of armageddon" or some other good books on how the US markets and banks actually work..

TLDR: financial crime pays in the US.
