People work their entire life and when they're rich, they think that working is the worst thing that could happen to them. Nature only allows the fittest to win. Somebody who never works on his own, is in no way fit, useful or in any sense going to be happy with anything he owns or will own. Switzerland is doing the right thing, by paying it's citizen for living. The citizen make the country worth, what it's worth, not the banks, not the government or anything else.
I can understand how they value that offer by that logic. It's always a risk, but that's what makes the game worth playing. 3 Billion is a lot, but their future valuation must be close to that, if they are sure enough to decline the offer. Alright dear traders, get your keyboards undusted and unleash your bids when Snapchat files an IPO.
