Hi Alec,
I can assure you we will never know how rich Cheney becomes after he leaves office because it is unlikely he will head another corporation, hence his income is not likely to be divulged publicly. However, he parlayed his former position as Secretary of Defense into the position of CEO of Halliburton. Now he has added Vice President of the United States of America to his resume (C.V.). Maybe a few lucrative directorships will keep the pennies flowing? In corporate America his resume will be looked upon as a diamond to display publicly to attract business and he now carries more influence than ever inside the government where astronomical sums of money are thrown at favored corporations. Cheney will capitalize on this opportunity to further enrich himself. Of that there is no doubt.
