Does the u. s. treat prisoners to nice compared to other countries?

Russia you get treated like trash if you don't something wrong, el Salvador got 98 percent of gangs off the streets making it a lot safer now. Their citizens absolutely adore president Nayib. He's a god fearing man. But yet the u. s. seems soft on crime we treat criminals like kings and queens there's no law and order at all. Everyone is to consumed in politics and obsessing over trump.
