Every once in a while some stalwart soul proposes “breaking up” the large tech companies—Google, Facebook, Amazon. I agree with them that the three companies are powerful, that they have monopolies which they have used illegally either to preserve their monopolies or to expand into other areas, both of which are illegal. What they haven’t proposed is how could they be broken up?
When John D. Rockefeller’s Standard Oil was broken up more than a century ago, it was done so along geographic lines. The same thing was done when the Bell System was broken up 35 years ago. How would you break Amazon? Geographically? The very idea is absurd.
That may be the reason that despite its bad behavior Microsoft was left intact. No one could figure out how to break the company up while letting the pieces remain viable. Basically, it was a mediocre operating system company joined with a mediocre development tools company joined with a mediocre office productivity applications company. The components mutually reinforced each other.
You could divide Amazon into a web services company and an online retailer. The online retailer might not last long on its own. It has lost money for most of its history and continues to just barely hold its own.
How about Google? Facebook?
IMO these tech giants can be regulated out of existence but there’s no practical way of breaking them up.
