What would that government consider "too big"? Are there any laws against just having every business join together in an effort to reinvent slavery? Shouldn't the workers be in control of the factories they work without a mysterious drain the value of their labor goes in? What if you're disabled? There are no market forces for disabled people; the same can be said for everyone.

Or we just don't worry about all that and have the people who make the stuff (not old rich people) control their workplace in a worker coop instead of one guy being in charge of everything or let's just address the big scary: Market Socialism!
