Covid vaccine and the deadly mandates to get it will continue this trend, as its doing in many countries.
How typically stupid for lefties to blame it on righties with no explanation, whatsoever.
I could give an explanation, if you like.
1) There's an attitude among the right in the US that "anyone can make it in the US"
The problem with such a statement is that it can be read in different ways.
a) if everyone puts in hard work, every single person will make it in the US.
b) if everyone puts in hard work, only a select few will make it
The first suggests that the reason many people are not making it in the US is because they're lazy or stupid.
The second suggests that money in the US is limited. That if everyone were hard working, there'd still be people falling by the wayside.
The topic here isn't whether you agree or disagree with such sentiments, but that conservatives, especially (there are conservative Democrats, Libertarians etc so it's not always about Rep-Dem), believe that the reason for someone failing is all down to themselves.
This leads to lazy politicians. They don't actually need to do much, because, well, it's people's fault they are born into poverty, and remain in poverty, even though their rich peers have a much better education, much more stable family life etc etc.
This lack of wanting to do anything about many of the problems associated with poverty exacerbates these problems. From healthcare to education to family life to drugs to gangs, it all gets worse and worse and gets harder and harder for people to get themselves out of such places.
This, of course, isn't the only reason, but I'd say it's a big one, and it's one of those reasons that differentiates other rich nations and the US.
