It is an honest question, and that's also the most controversial point. The initiants ask for a min wage of (raw) 4000 CHF per month which is approximately 3000 CHF net of taxes. Why this number ? People pretend that's what one need to live well. The reality is more complicated than that, as you may guess, the cost of living really depends on the region and on the industry sector. That's why opposants want to solve this problem with per industry sector conventions (ie: there is already a minim wage in the watch industry) rather than with a global try-fix-it-all law.
