That would not lead to prosperity.
It would lead to more loans/leverage meaning more money is out there buying the same stuff, which leads to competition in buying which leads to higer prices.
Increased money supply leads to inflation.
Secondly, investors loose interest in interestbearing intruments and more likely move their money overseas where the interest rate is better.
Similarly there is little incentive for people to save money as prices are shooting up and interest rate on saving is low.
This leads to people borrowing more (as it is cheap) and buying stuff, which constantly increases in price = hyper inflation.
Do some search on Weimar Republic for excellent case.
Finally foreign investors seeing the currency weakening and interest rates being low would move away from the currency leading to a currency crash = expensive imports.
For a nation that isn't exporting or at least self sufficient in produciton of goods, this would lead to a drop especially in consumer discretionary spending, which then leads to unemployment etc.
Not a totally comprehensive explanation but at least to get you started. Secondly I suggest you spend some time at
Safehaven and read up as much as you can.
