Yes, it is harder to implement changes in a large system than in a small system. However, you should note that Switzerland is more culturally diverse than the United States by a number of metrics, including immigration. For example, 25% of the Swiss population are foreigners, three times as much as in the US. Also, Switzerland has three official languages. Consequently, there is no national TV station or newspaper that can reach the whole country at once. But if it helps you, I'd like to mention that France also has a wealth tax and that Germany had a wealth tax until 1997.
