Why shouldn't he take advantage of tax breaks? Most people do. Saying he shouldn't take advantage of tax breaks that is readily available to him is about as nonsensical as conservatives saying that if liberals want to raise taxes, they should voluntarily send money to the Treasury and not force everyone to pay. Same coin, different sides.
You realize that his tax return is irrelevant to determining his involvement in Bain, right? He would continue to receive partnership distributions from carried interest from past funds and profits from the management company whether or not he was actively involved. This was investigated when he ran for governor in MA. This whole "Was he running Bain" garbage reminds me of the birfers demanding to see Obama's birth certificate years after it was certified.
If it doesn't matter, why is Mitt reluctant to release his tax returns?
From what I understand, he wasn't just getting distributions, he was being paid a salary of $100,000 a year. While he "wasn't there" doing anything to earn a salary.
When he ran for governor is when he used his Bain tenure as proof that he really "was there" in MA and therefore qualified to run for governor.
