I'm sorry. I didn't catch the end.
I think more good people would be encouraged to enter politics if they knew that the ethics standards across the board were strong for everyone. Then, knowing that conflicts of interest are prevented, prohibited and penalized, and therefore discouraged, they would know they wouldn't be tainted as being guilty by association with some other public office holder who is there to serve themselves and is caught and exposed.
Again, I think it's entirely possible through tax breaks to create an incentive for people who are wealthy and have investments to enter the public service. Just give them a tax break for serving the public on the capital gains they have from their investments. That would be a great financial windfall for someone entering the public service. Invest in GICs and government bonds, earn a fixed rate of interest while you're here, serve the public and then leave. When you leave, go back to serving yourself.
