LOL. You serious? I'm not even talking about Canadian retailers vs American or multinational retailers. Ok, let me break it down for you in language we can all understand:
If I buy from the Footlocker at the mall, or Footlocker.ca, who do they employ? Canadians and permanent residents. Those employees all live here right? They're going to hit up the food court for lunch and buy themselves some food from a place employing residents of Canada. That money is, more likely than not, going to stay here.
Now, say you buy from Footlocker.com to save $40-50. Who do they employ? Americans. So, where do you think these Americans are going to spend their money? They sure as heck aren't going to come up here to the Eaton Centre Food Court are they? That money, more likely than not, is not coming back to Canada.
By taking away a sale from the Footlocker up here, you decrease their sales, which then leads to a decrease in staff. The decrease in staff leads to less people eating at the food court at EC, etc.
If you want a larger scale example of why globalization can be harmful, you need look no further than the outsourcing of call-center jobs and IT departments to foreign countries. Canada lost a ton of jobs all because greedy corporations wanted to save money in wages paid and line their own pockets. 50 years from now, the gap between the poor and rich will be huge. We won't have a middle class.
I understand multiple languages. Try me...
You do understand that I did mention in my post that the benefit of having US retailers in Canada are the added jobs right?
Your point about employees purchasing food in Canada is horrid. You're telling me that you truly think the government as well as corporations are thinking of where their employees purchase their food? Hah, alright... Additionally, while Footlocker.ca might have Canadian employees, not all of the larger companies do. So they might be ordering from In n Out. Or they could be buying their dinner from McDonalds Bangladesh.
Again, you're not getting my point. Whether they're buying from Footlocker.ca or Footlocker.com, retail is going to get affected regardless so the in-store jobs will either get undercut by Canadian online retailers (which don't always employ Canadian residents. So unfortunately the Sbarro in the Eaton Centre will probably still suffer...) or by US online retailers.
Looking at your larger scale example, who doesn't the government tax companies for having foreign production and IT jobs? Why does the consumer/local have to pay extra for products? Anytime you see made in Canada, you're in for a much higher price than made in other countries.
Like I said, I know the space well because it's part of my job. It doesn't make much of a difference to the government.
