As a Swiss I agree with the above. I think it also helps that there is no concentration of the executive power in any single person. The Federal Council ( https://en.wikipedia.org/wiki/Swiss_Federal_Council ) is made of 7 people from different parties who have to agree and work together. I think this is much better than the system in place in much of the world where executive power is concentrated in a single person who is effectively an elected king with a few restrictions.
