Break up monopolies and deregulate them.
Break up monopolies. Proper USA government has done this before because we want competition. It is the nature of corporate business to collapse similar businesses onto themselves. This needs be undone on a regular basis.
Consolidation mostly stems from the artificial nature of legal fictions, sans corporations. Corporations last much longer than the real people who create private enterprise, so they accumulate this way.
Corporate grow and ownership of much of our resources is a function of _money_from_thin_air. We would not have such monstrous corporations without it. Fiat money is the _food_ for these legal fictions and for fiat government, like that one occupying DC.
