Are you suggesting Harper purposefully had party fundraisers with him in attendance and had billionaire attendees later pour millions into his own foundation and accept thousands of dollars to build a statue of his father? 
I only remember fundraisers being organized and attended by low rung party officials like it should be and the odd senator like Duffy which caused a lot of rightfully deserved backlash.

By moral standards Harper is a saint comparied to the snake we presently have as PM
Harper was also a reasonably inexpensive PM as he did far less holidaying and finding reasons to be MIA globetrotting rather than being in the HoC.
