Swiss to vote on 2,500 franc basic income for every adult 13 years ago
This "might" lead to people actually working more in a certain sense. If a person is to receive an X amount of francs per month then employers will require 40 hour / weeks leading to approximately 15 francs per hour (€12.5), which for a place like Switzerland is kind of fair.
Those who choose not to work enough might have to face inflationary affects in housing etc. needing to catch up to the median (not average) population income levels.
Eitherways, if the Swiss go wrong on this their system of voting is flexible enough to allow for change back.
