Most of that was just politically motivated stuff. The difference is that the trove of emails was not filtered and research discovered the potentially implicating campaign finance stuff within that trove.

The personal wealth was likely done in a way that does not violate any laws. A donor can make a book deal happen with a $2M advance rather than violating laws by donating $2M. That's gray area but not surprising or concerning.
The potential area of concern is the way that the Clinton Foundation may have been used to collect donations from foreign governments in a pay-to-play arrangement. I'm not entirely sure whether it's reasonable that such things are illegal, but they are illegal so if someone is doing it we should all be concerned.
I'm pretty concerned about Paul Ryan's $8M as well. You didn't address this so I am guessing that you assume it all to be above board?
And as far as Clinton's personal wealth, 15 years of book deals and 100k speaking engagements will create quite a nest egg. Let alone starting their careers as high powered attorneys. There's nothing unexplained here.
