You are very right in your submission that multinationals grow into Morales's and inhuman monsters, however I don't think restriction on jurisdiction of trade (what you call sales range) is achievable. Reason being that multinationals did not just become what they are, they became giants by consuming their rivals through "quality" of services and goods they rendered. So far people will move from one society which may be jurisdiction of one company to another which is the jurisdiction of another company) news of one quality product will not let the people stick to the one produced close to them. Don't forget sentimental values also have a role to play in this. Chinese people may reject African noddles for theirs because according to them their noddles is the best. This will cause smuggling of product from one society to the other.
What I think they can do is for government to legislate on profit. Sincerely, the idea of profit is the first of all scams the human mind could come up with. Till now nobody determines what percentage should be legally accepted as profit. That is through what common people of this days are swindled. If government legislate profit you make from a locality must not leave that locality, multinational corporations will die a natural death.
