Every new market you introduced your product in brought along with it a layer of bureaucracy and middle management, which left you more bloated and unwieldy.
This allowed smaller,local companies to have an agility and responsiveness advantage even if they offered the same service at a higher fee.
Computers and the internet have made the process of expanding a lot smoother with instant inventory management, communication etc.
Not sure what government can do to stop this. The more power you give to the government, the more lobbyists and corruption it will result in. And even if they do manage to sign some legislation, there will be workarounds and loopholes.
I am struggling to even think of rules that would efficiently limit the growth of Amazon,Google etc. Cap their market share somehow? Tax companies which have more than x% of market share at an exorbitant rate?
