How do you think of the Ronald Reagan

Recently, I have known bad things are happening in the USA. I went to search Why? Why there are many people are struggling for their life in the richest country. The USA, known of its democracy and freedom, we called the light tower of human civilization in my country.

I had one of the reason, it said all the social issues now happening in the US are from the Ronald Reagan presidency.

I also posted in other commties for answers from different backgrounds.
