Wow, talk some more about not being able to form sentences. The term you are thinking of is "tin can" not ten can. People used to make things out of the used tin cans their food came in. To say something is made of tin cans means it is made out of garbage.

Second, "the south" is not a thing on its own. The south of what? When people say "the south" without any other context they are usually talking about a culture that is roughly located around Mississippi, Tennessee, and Georgia. It has nothing to do with cities or economies.

The south of the US has some of the wealthiest cities in the world including Austin and Miami. No one with any shame or intelligence would claim that the southern half of the US is poor and going bankrupt.

What you probably heard was the UN talking about "the global south" which is just a bullshit term they invented to replace "3rd world country" because they feel that is a hurtful term. The UN is a joke.

The US has a shit ton of welfare programs. To say that no one is helping poor people in America is wrong, and incredibly ignorant.

And saying that there are poor white people "in the south" does not even have anything to do with history. You clearly have had too much propaganda thrown at you and you can't keep it straight. Is it history or economics or class structure or muh evil capitalism? It's all just a jumbled mess of half formed ideas, and you can't even tell that it doesn't make any sense.
