Russia has cut its Sochi 2014 budget by 15%, and that would mean they would save about US$8.3-billion......and that's just 15% of the entire Olympic budget, so you can basically do the math on what their total budget is.
And yet, Vancouverites complain about Olympic costs that would benefit the city for decades to come.
