C. Boyden Gray, the lawyer involved in the suit challenging the constitutionality of the CFPB, writes in the Washington Times that "the new regulatory regime primarily helps the big banks while placing its heaviest burdens on community banks.”
He points to data that since Dodd-Frank was enacted big banks have gotten bigger both in terms of asset size and deposits and have also outpaced the economy.
It's not just a matter of small banks getting crushed by the new regulatory burdens, he argues, it's also that "systemically important" implicitly signifies "too big to fail." And that "status can attract investment capital much more cheaply," he writes.
