I admit I do not like the subject of this thread. In fact, I seriously object to it.
I see no need for the US to “improve”. I see no need for any individual country to ”improve”. In fact, I could name several countries and the way I think they should improve. But it is not my business to do so.
Nor is it the business of anyone, who is not an American, to comment on any improvements they feel the US might need. People who live in glass houses should not throw stones.
Everyone, especially Americans, must remember that the US is a “young” country. Older countries, Great Britain, France, Africa, the countries of the Middle East, are older and have just as many concerns and just as much a need for “improvement“ as the US.
The US is having elections now that may or may not change our way of life dramatically. This is an especially bad time for a thread like this, IMO. And, as usual, this thread has wandered off topic as many threads do.
What needs to improve? The world. All the nations of the world need to improve. That is my opinion and I am sticking to it.
