It's not even governmental stuff; one of the sticking points we have is our payroll package, which doesn't support foreign places like "Wyoming", "other countries", and "Indiana."
The same issue probably applies to our health insurance plan - it's only useful in the U.S. and would also be expensive to change.
A health insurance plan isn't much of a perk for many countries outside of the US that have universal health care.
In that scenario I wouldn't care if that was only available to in-country employees, the same way that I wouldn't care about missing out on perks like catered lunches.
