the debate leads allan sloan looking to hire mitt romney as his tax accountant. lan is senior editor at large at "fortune." >> if the presidential thing doesn't work out for mitt romney, there's a whole other career he can pursue-- retirement planner. romney has gotten what is probably the greatest retirement package in history. even though he left bain capital in 1999, romney still gets millions a year from bain's piece of the profits that investors get from bain's buyout funds, and pays only 15% federal tax on it. in some years, less. compare that with my social security benefits. my wife and i pay 30% tax on those. that's because 85% of our benefit is taxable, and we pay 35% percent on that, thanks to the a.m.t. this all happens because, under our current tax system, income from capital, which is how romney's bain payments are treated, is much more valuable than income from work, which is how social security is treated. i have no idea if romney would make a good president. but if he wants to offer retirement advice, i'll be his first client. i'm allan sloan. >>
