If your comment was true Bill Clinton would not have pushed NAFTA through Congress, and he would not have repealed the Glass-Steagall protections. Both were gifts to large business that allowed them to grow and further their monopolistic interests. Bill also removed the national cap on commercial radio station ownership , which led to major consolidation of the news/media landscape with the telecommunications act of 1996.
Obama oversaw major mergers in Pharmaceuticals, Telecom, and airlines and didn't use the Sherman anti trust act on a single company. His affordable care act encouraged consolidation in health insurers, drugstores and hospitals to the detriment of the citizens.
Democrats being for the people and anti-monopoly only exists in speeches not ion action.
