When the people are ready a leader will appear. If not Mr Trump, who? You perhaps.
I think the people have been ready at least since W's two big amnesty pushes in 2006 and 2007. No leader appeared then.
It takes quite a leader to go against practically the entire political establishment (both parties) and appeal directly to the people successfully. Such leaders are few and far between.
I'm afraid the leaders don't always arrive when the people are ready.
