There's probably more piles of rubbish in the US than there is in Mozambique... and I'm pretty sure some of them fall over from time to time. The only difference is, people don't (as far as I know) live next to giant piles of rubbish in the US. Health regulations and what have you.
But still... just because some people choose to live next to a pile of rubbish, probably through necessity, doesn't automatically mean that they live in a shithole country.
