So far, there were about 2 or 3 unconditional income law proposals in the last 10 years, and they were all voted "no". Thankfully. Because "unconditional income" will not magically appear from nowhere, it will be provided from my salary. And my company's income (at this point, I have to pay around 18,000 francs per year even if my company doesn't do anything to finance all social programs already there — so much for "unconditional income"). And I have to pay another 6,000 francs per year for obligatory medical insurance in Switzerland. And I won't be able to receive this "income" anyway, as I am not a Swiss citizen — I just live here and have a company here, and I have to pay _a lot_ for this.
Money don't grow on trees. It always have to be sourced from somewhere. And not from some nameless "rich corporation" — it will be sourced from my already struggling business. And from yours. And from your salary.
