Every country has problems but for most of these countries it's to be expected. A small country with unstable politics and a developing economy is bound to have issues. The USA is a global superpower with immense influence on the world stage and quadruple the money of the next richest country, yet it struggles with problems most advanced nations have a handle on.
Women dying during childbirth. Adults being illiterate. Cops killing and abusing power. Most of America's peers don't have these issues. America is ranked next to small third world countries in these stats and many more. America isn't mocked because it has problems. It's mocked because it has problems it really shouldn't have.
