I know this doesn't fit your view, but oil companies aren't making cheap plastic toys or trendy electronics. Rigs are complicated and they pay competitive wages to attract the best qualified which is who you want working your equipment valued in the 100s of millions of dollars.

By opening the door on for foreign investment, it potentially can reduce the corruption as most companies won't invest in resources that are ripe with corruption...its unstable.
