A soft cap on corporate size seems like the simplest solution.

EX: 20,000 employs and or contractors and companies can’t own shares of other companies without being included in that cap. Outsourcing seems like the obvious loophole, but hardly an insurmountable barrier.

Though, increasing tax load as companies scale is probably a much better option. Not that there is a realistic chance of this passing any time soon, but large companies are harmful to both democracy and free markets so it's likely to be tried by someone.

PS: The only real counter argument I can think of is global completion.
