If this comes to a vote, this will be voted down just like the recent popular initiative that demanded 6 weeks holidays a year for every employee. The Swiss electorate is very careful - and mature I think - when it comes to voting on economic proposals. Any proposal that will lead to a massive rise of public expenditures or harm the country's productivity and international competitiveness has usually no chance.
Switzerland is like the US, except it functions properly. Wow. I am in awe of the Swiss voter right now. Democracy can certainly work there.
