Who thought China getting this was a good idea?
Honestly... anyone in winter sports and their dogs. Winter Olympics are slightly different and pretty much unrelated to what some weird guy in some well guarded house thinks
When you try to sell some winter equipment, and you have fully saturated market of about 5 million people, and then you have market of 1.4 billion people where winter sport doesn't really exist yet, and winter olympics might fire it up, I guess it's not really all that much of a question where you would rather go, or is it?
Another thing is also who really wants to host Olympics. It's not so many candidates anymore. Sure on beginning there's whole bunch of interested cities/countries, but when "race" is closing and local communities starts to get involved, pretty much everyone are strongly against Olympics. First it's insane money that hosting country/cities needs to invest with basically no return. I have no idea which were last Winter Olympics that were profitable. And then it comes out, what it came out in Norway, what insane demands IOC has, and it's no wonder, you end up with list of maybe 3 countries, that might still be interested to host them for anything but sport reasons.
But purely from winter sport industry view, you can hardly find better country then China for this.
