It's not intrinsically a bad thing (some may hold that opinion, though). However, if you are investing in Bitcoin because it is similar to gold in that scarcity is a primary attribute, then the ability to mint new bitcoins is dangerous.

I'd also posit that "because America does it" is a fairly weak argument for many of the claimed benefits of Bitcoin. Much of Bitcoin's charter is that it helps move away from government-controlled currency. If you think America's monetary system is the best option available, then Bitcoin likely is not your thing.
