One thing that changed my viewpoint was this book. Deaths of Despair and the Future of Capitalism by Anne Case, and Angus Deaton.
In it, they make a point that, almost all US economists agree that immigration, both legal and Illegal Immigration, is not the cause for American working middle class failure. It is lack of education, and capitalistic system wherein rich steal the money from the poor, which is like a reverse robinhood.
Hacker news crowd can easily verify this by spot-checking. But still we fail for the false narrative and divisive exploits of immigration topic, which is certainly not aimed to solve the problem of American well-being at hand. Truth to be hold, politicians know this too.
