"They turned Bill's post-presidency and Hillary's potential one into a cash cow known as the Clinton Foundation that certainly has done much good in the world but also conveniently allowed them to live in the style to which they had grown accustomed in the White House: The private jets, rubbing elbows with the uber-rich, fancy dinners and hotels."

This is unfair. I don't think former Presidents and their spouses (especially those who serve in the Senate) are ever short of opportunities to take private jets and hang out with the Davos crowd. From all credible reports (meaning mostly those non-profits that rate other non-profits), the Clinton Foundation was well-run and did what a good foundation was supposed to do. That it was well-run probably let the Clintons overlook just how terrible the optics were of allowing the Foundation to solicit large sums from donors while Secretary Clinton was in office, in fact.
