I think you guys are referring to the system known as 'Fiat' as compared to a 'Gold Standard'
In the past, all the money in the world was linked to the amount of actual Gold the government holds in their vaults. More Cash/Same Gold = lower value of money
Now, the Governments like the US can simply create money out of thin air as long as they declare it legal tender simply by printing more. However, More magic cash = lower value of money
nothing to do with political systems here.
However, the reasons behind it has to do with politics and economical reasons including leading to inflation.
