You absolutely can, and we absolutely have. You believe this because anti-trust action was derided as anti-growth in the latter quarter of the 20th century, by people who knew exactly what they were doing (see also: banking deregulation).

It's one of the major reasons we're stuck with such horrendous corporate and individual wealth inequality today.

Google should never have been allowed to buy DoubleClick, ship a browser, or ship general-purpose client operating systems.

Okay fair, you can avoid a monoculture with the legal system. Bit late for that now, unfortunately.
