What information gives you that conclusion?
I stand corrected; only the expenses that are related to compliance are deductible. However, as long as members of Congress can receive political contributions, legislation is influenced.
Corporations will still try to influence legislation, even if not deductible, so long as the proposed legislation favors them. Bank of America influences bankruptcy legislation. Pelosi’s husband influences minimum wage law, getting himself an exemption.
Drain the swamp.
