One could argue that foreign companies should pay a license fee to the US, to be allowed to make and sell devices using the GPS signals. If even possible, I think that’d be counter productive, and I think that “at our expense” is a bit much. The cost and function of the system is what it is whether non-americans use it or not.
You might be aware of this but the american GPS isn’t the only GNSS (Global Navigation Satellite System), but it was the first one to become open to the public. Many new devices are GLONASS (Russia) capable, for example the iPhone 4S.
I suspect that devices will continue to be called GPS whatever GNSS’ they are using, as I think it is understood in the public mind as ‘satellite navigation’ rather than one of several GNSS’.
The Chinese have a GNSS called Beidou (the Big Dipper), and is in the process of deploying a new system called Compass. The EU is also deploying a European GNSS called Galileo, and India and Japan are deploying regional GNSS’ to be used with GNSS’ for greater precision and as a military fail safe. By the end of this decade we will have four GNSS’ and a couple of regional ones.
It seems as if all these systems are open to civilian devices, and that they can be used synchronously for greater precision. Together with governmental and commercial ‘GNSS augmentation’ we seem to be apporoaching a global navigation down to the centimeter level. The global civilian possibilities and applications for mankind are incredible.
One other exciting aspect with the improved GNSS’ is that they will be able to send signals back to devices in case of a distress, and I’ve understood that for example many Chinese fishers are using their satnav system to send text messages to their families while at sea. Greatly needed and appreciated in the worlds biggest fishing fleet.
I think one might keep in mind that these are – with the exception of the EU GNSS Galileo – all military systems and no civilian have a special right to use them just because they pay taxes, american or not. Most military systems is not accessible to civilians. In order for American civilians to use the GPS, it must be open to everyone.
Them being military systems is of course the reason for why there are increasing GNSS’ deployed, that the GPS will be removed or jammed for everyone except the US military and associates in conflict situations. I suspect that the Brazilians and USAN will come up with their own GNSS in time.

I can’t see that a suggestion for that countries would be paying the US for keeping bases that the US itself choses to keep there or conduct operations to support it’s own interests, would carry very convincing arguments.
