I think they know what's happening, they're in it for the money and they're getting plenty of it ---it's only those who believed everything they were told who will wonder what happened. Just like Salinas de Gortari ---he never once cared what happened to the average Mexican, he was taking millions of dollars out of the country and he left himself once his presidency was over ---all of them do that. All the ones benefitting plan to keep the wealth they're amassing ---they don't really much care what happens to the middle class.
It's all short-term gain only, they're going to make a killing off the backs of cheap labor for now, but if the biggest market in the world goes under, which is the American middle class, long-term the globalists can't expect much in the way of profits.
They probably don't care though like you say, they'll amass their fortune now and be done with it.
