The notorious disregard for the oath of office in the Federal Palace also has clear negative effects on the economy in Switzerland.

However, the greater concern is for the freedom and independence/neutrality and thus the security of Switzerland. 
Reto Brennwald has scratched the surface of the problems with beautiful images:

Switzerland is one of the most successful countries in the world. Its inhabitants are free to take their fate into their own hands. But these freedoms are diminishing, as the state's share is steadily growing. Bureaucracy, regulations and controls are taking the place of personal responsibility and entrepreneurship. This film [1] shows where this trend is leading. It asks why we are increasingly delegating to the state instead of taking matters into our own hands. And thus recalls what was at the origin of success.

In "Corruption & Abuse of Power - The Dark Side of Politics!", Claudio Grass and Daniel Model go a bit deeper [2].

We are clearly being lied to about inflation. Who can believe that prices are declining? One only needs to step outside to see the opposite. The shameful decision to reduce customs allowances shows that our authorities support cartels and the impoverishment of the middle class.

Moreover, bureaucracy and taxation (or the search for revenue by the tax administration) and barriers to trade and travel continue to increase. The strong franc continues to cost us tens of thousands of jobs and does not benefit consumers due to lack of competition...

At the same time, we are paying ourselves a 13th month AHV pension just a few months after increasing VAT, and unnecessary expenditures continue (traffic obstructions, renovation of roads in good condition, explosion of healthcare costs...).

SMEs, especially those active internationally, suffer the same fate as consumers. Slowly, our competitiveness is being exhausted and we pretend not to see it by repeating that it's still better than elsewhere.
