I currently know a successful attorney who is being recruited to run for an open seat in Congress. He’s mulling it over, but I think he’s going to do it.
At this point in his life, he’s a partner at a firm. I don’t know how much he makes per year, but it’s got to be solidly in the six figures. I also knows that he owns lots of real estate (about 12 homes, which he rents) and is a part owner in a restaurant.
If he did win office, he’d have to give up the attorney position, but he’d still be pulling in the income from the other investments.
And, of course, if he left congress and returned to the law firm, his name recognition might dramatically increase his income once out of office.
My guess is that he’s likely typical of the people who end up in Congress - they are quite successful in their field, and have lots of passive income, with the further ability to earn even more once they leave office. This helps make them wealthier than a congressional salary would seem to offer, but it’s not corrupt.
Meanwhile, politics can beget wealth in other ways. As noted, speeches and book deals can be lucrative. And since we don’t expect politicians to be permanent, they may return to the private sector and be rewarded for their efforts to pass laws favorable to the industry. Is it corrupt to hire a former congressman as a senior executive after he helped deregulate oversight of your company? What if he merely helped the company secure government contracts?
I’m reminded of the example of Dick Cheney. He was Sec Def during the first Gulf War. As part of that effort, the defense department paid millions of dollars to Halliburton to determine if privatizing certain military operations was feasible. They said it was, and then got the exclusive military contract to do so. Cheney then leaves office and becomes their CEO - making tens of millions of dollars - before eventually returning to politics as a VP (where he again facilitated Halliburton contracts).
Now, I think that’s shady as hell. But it’s not corruption in the sense that you can outlaw it.
