Agreed the big reason that international businesses come her is the low cost for labour. If you want more proof answer this question.
Why do Canadian and American companies buy things from China and have their factories in China and Vietnam?
It was not that long ago that many of the textile companies were here and bras ad other clothes were mass produced here.
Also the thing that people do not take into consideration is the affected cost. A Good example is STARBUCKS and Tim Hortons.
The actual coffee that they sell is cheap and the price does not rise or lower that much. However, the cost of employees is their biggest cost. Not only the hourly wage but the taxes and government charges (as most of these are a percentage of the salary they go up too).
So the only way that Starbucks can survive is to close shops, fire employees or raise prices.
Bottom line is that while yes people need to make more money and yes some things are getting crazy with pricing the government has to be careful.
Higher costs means less full time employees meaning that instead of people trying to make ends meet with the current pay many will be looking for work as factories and stores close.
