There are two big problems with this article:

1) When discussing taxes, the article says " In other words, the Alberta NDP plan effectively raises taxes on those earning more than $180,000 and cuts taxes on those between $50,000 and $180,000." which is a good thing. But it then goes to compare those under 50k to BC of the same earnings. The comparison being made here, though, isn't a result of the Alberta NDP plan. It's always been that way. The people earning under 50k aren't experiencing any change.

2) The opportunities that companies look in Alberta for don't exist elsewhere. They aren't going to say "we can drill for oil in either Ontario or Alberta. Oh, look Ontario has a half percent lower corporate tax rate, guess we are going there!" Companies are in Alberta because we have a resource. Say what you want, but Oil drives Alberta. We would be a much different province without it. So companies coming to Calgary or Edmonton are here because there is an opportunity, either through Oil or through services that they can provide to our residents (who are here because of oil). What articles always fail to highlight (because, lets be honest, this article seems targeted towards the less knowledgeable) is that corporate tax is on profit, not revenue. Any opportunity that was here before is still here. So you lose 2% of your profit (if not considered small business, remember they aren't seeing a change), but you still profit.

The real concern I have with the NDP plans is that they want to 1) increase royalties, 2) increase corporate tax rates, AND 3) increase minimum wage. All those three costs COMBINED might push away business. The corporate tax rate alone is totally fine.
