Follow the money!

Fox News is reporting that the UAW owns a $33M lakeside retreat and a $6.4M members only golf course. I understand that members interests are being served here, but where did the money come from? I wonder if union dues paid for these perks? And if so, its no wonder the employees represented by the unions need such high wages... I'm not against high wages, but the type of tithing the UAW requires of its members is something along the lines of the rumored 15% tithe required of some religious organizations, many of which the UAWs top brass would wail about given the chance. I wonder if they might draw the same comparison?
