I would certainly draw it much closer to the public interest that it is now by most countries.

In particular, "platform" businesses like Visa, Google, Amazon, etc. should at a bare minimum restricted from competing with the users of their platform. Ideally, the social value of the platform would be made public by a government buyout (aka nationalization) instead of flowing to the hands of the few select shareholders of the platform or subject to the whims of the platform company's executives.
