Well like if everyone was suddenly set to have 10 million US dollars in their bank accounts and all debts canceled, there would be an immediate inflation as most people would quit their jobs immediately and getting services provided would become practically impossible to anyone that doesn't do them themselves, not to mention the fact that goods would also become absurdly expensive as no one would bother with the task of selling goods when they already have so much money on hand.
However, due to the sudden lack of goods and services this would destabilize the entire country, and there would be riots in the streets.
After all of that hubbub was dealt with, things would generally return to exactly the same as they are right now as the extra money flows into the hands of those who have the most goods and services to offer and the machines with which to create more goods, and eventually those who do not have the institutional advantages would return to being poor due to their lack of having institutional advantages.
