I fucking hate when people say this. As someone who lives in a Developing country, hearing people say that their safe suburban lives are akin to a third world country is insulting. Just because there's crime, does not mean it's a third world country or anything even near it. It's frankly offensive that one would even insinuate that the richest country in Earth is third world because "uhh Biden or something."
This is not to say that America is perfect. It's not. There are many improvements to be made. But the quality of life of poor people in America is far better than that of a poor person outside of the US. Do not act like problems needing to be solved makes America third world in ANY way.
