“Governments should copy Switzerland and impose a spending cap. I explained this system in a column for the Wall Street Journal back in 2012.”
…85% of its voters approved an initiative that effectively requires its central government spending to grow no faster than trendline revenue. The reform, called a “debt brake” in Switzerland, has been very successful. Before the law went into effect in 2003, government spending was expanding by an average of 4.3% per year. Since then it’s increased by only 2.6% annually. …politicians aren’t able to boost spending when the economy is doing well and the Treasury is flush with cash. Equally important, it is very difficult for politicians to increase the spending cap by raising taxes.
