This is a disingenuous comparison because the US dollar and most fiat currencies never increase in value medium to long term / "deflate" by design. The decreases in the value of the dollar are never offset, so if a basket of goods goes up 5% we bake that in forever. In the UK I can't really think of a time when inflation has stopped or reversed for even a few months. By contrast Monero goes both up and down. So sure, it's unstable, but it doesn't have "higher inflation", it's just more volatile.
