why not eliminate geographic compensation zones worldwide? It has many cons for employees, but 'at will' employment presents benefits to employers that can be reflected in salary, since if that employee is no longer needed or the salary is no longer viable for the business case, the employee can be let go easily. If you're employing people in countries where you have to spend months of negotiation, legals, or may even be unable to lay someone off at all, you're not going to be paying as much, since you need to cover contingencies. If US people move to such countries, they can also be covered by such laws, or may also be subjected to double taxation which will affect their pay too. I know people in Europe who've been "employed" by US companies as contractors to avoid having these local legal obligations, and that would certainly open up the option of global pay levels, but I know there are legal and regulatory issues around this approach too.
