Cost of living aside, average wages in other countries are generally higher, but after the conversions things are far cheaper in many scenarios.
EX: GTX 780
USD: 650
AUS: 750 (673 USD)
23 bucks more. My buddy at McDonalds makes 7.25/hr=1,160/month before healthcare taxes etc
Friend works at McDonalds in AUS makes 16.23/hr(14.79 USD)=2366(USD) before taxes
For all intents and purposes, lets assume healthcare and taxes are 50% of wages.
2366/2=1183
1160/2=580
This is all converted to USD
1183-673=510
580-650= (-70)
Case and point, cost of living maybe higher, but electronics are still cheaper in average wages earned vs cost. AUS makes 2-2.2 times more than USD, but pays 5% more for electronics. If cost of living scaled equally to be 2-2.2 times more than america, then a GTX 780 shuld cost 1300-1400 USD over in AUS, but it costs 673 USD in AUS.
