Why has the United States over the past century culturally declined worse than Argentina?

Asking because we tend to think these things are downstream of money printing, and money printing in Argentina in this period was orders of magnitude worse than the US.

But in terms of the average population, the masses, people seem to be in better health here, dress better, have less addictions and eat less junk.

Is it the ability of printing a stronger currency? Massive corporations and using the American public as guinea pigs?
