The distinction is quite relevant to the narrative. If your narrative is that the laws and prosecutors unfairly put people in prison that don't belong there, then you want to compare the percentage of people who ever go to prison, not the percentage if people in prison at any given time. The latter fact is relevant to a narrative that our prison terms are too long, but that's a distinct problem.
Also, we do have higher rates of violent crime than our peers. You can't ignore that.
And while its phat to blame the lobbyists, I don't think that's the entirety if the distinction. Americans are simply more retributive than other people. Look at the death penalty. It's 2012 and half the country would be up in arms if the Supreme Court declared it unconstitutional. At the end of the day, prison terms are long because being "tough in crime" got a lot of votes in the 1970's and 1980's.
