There will always be an elite of wealth -- the egalitarian ideal, the reputed folk wisdom and virtue of the Common Man is a myth of dubious merit, given the tribal prejudices of so many common men. When people on either side of the political debate complain about "elites" (as Trump voters, or Ford voters locally) they are being disingenuous; what they really mean is to that they want to replace the current elite with one more to their liking, i.e. a liberal one with a conservative one or vice versa. 
The trick is to keep the moneyed elite from dominating your democracy. Controlling the outrageous cost of political campaigns, enacting term limits -- and most importantly, giving more financial aid to students without family means -- would be helpful. 
And if you really want them to take their wealth elsewhere, our tycoons will shrug and move on to a country that wants them.
