US Incarceration rate: is it a plan of suppression

US Incarceration rate the highest in the world http://en.wikipedia.org/wiki/List_of_countries_by_incarceration_rate a whopping 743 prisoners per 100,000 population. For comparison, India has 32 for every 100,000 population!! 1 in every 32 adult is in prison or on probation...

Some aspects / interpretation

1. US has lesser tolerance to differences with in it's own population. Why can't we let some one who commits non-violent crime continue to be part of the society?
2. Privileged, Richer and intelligent people, don't want to and don't like to live among the under privileged people - who tend to be incarcerated more often than the rest of the population.
3. US condemns the rest of the world (Most of the world population) for 'freedom' and 'human rights' violation. Isn't incarceration a form of extreme deprivation of 'freedom' and 'human rights'? Who will fight for this cause?

This data was highlighted by Iran's President Mahmoud Ahmadinejad on one of his speach.
