I voted yes, but hear me out. Crater or Create, we need a direction for this city.
Yes, all the details right now look bad, but IMO if the Olympics are coming regardless, then large swathes of the city will move towards making sure that they can benefit from the game (as opposed to get bent over).
The O&G side (Pipelines > Olympics): Seriously, the city wouldn't allow the economy to look desolate before the games arrive. I bet it's a you scratch my back, I scratch yours. O&G gets a boost, and then those same companies pour into the games in one manner or another (deductible for tax purposes of course). O&G gets a kick in its step as opposed to languish, the games gets some key sponsors.
Taxation of the average Calgarian taxpayer: I really cannot see how city hall would do this in a way that truly screw us. For one, the Olympics are how far away? They'd be voted out long before it's their legacy. They'll do what is necessary to appease us to stay in power. The city would pour money left right and centre into our city to beautify it. Taxes may go up for us, but they'll definitely be working super hard to find money outside of Joe Schmoe's pocket (Federal, Provincial, corporate etc.). Raise it later? Again, booted out before it can be done.
Odds and Ends: IMO, if the games come here, money will come. I think the bigger issue will be the man power. Vacancy rates downtown will plummet as random groups fill them (if not O&G, someone coming to try and get a slice of the Olympic spotlight pie). Local businesses may find incentives to help the city meet a specific goal. I think there might be a spike in business other than O&G (ie: infrastructure, construction, tourism, logistic, tech, Cannibis etc.) Plus with what we're putting in the city, we can put it to good use, rather than other cities watching the Olympic infrastructure crumble a few years later. I think we enter into another unsustainable explosion of growth if the games come. But one that we can find a way to absorb and reduce the economic boom hangover by diversifying our economy. Denver is the model I think we need to look at in terms of diversification...
Like I said, Crater or Crumble, we need a direction. I feel like we've been standing pat for a few years now and that screw all parties involved in the long run. Good or bad, we need a direction to run. Canadians unify when there's a reason to do so. I think we can sort that out along the way.
