Should high capital income be taxed more to reduce taxes on salaries?

AI-generated summary, admin reviewed: This initiative proposed taxing high capital income more heavily than employment income. Capital income such as interest and dividends above a threshold to be decided later would count as 150% of its actual amount when calculating tax. The campaign suggested a threshold of CHF 100,000. Additional revenue would be used to reduce taxes on people with low or middle employment incomes or to finance social benefits. Supporters argued that income from wealth should not receive more favourable treatment than income from work. Opponents warned that the unclear threshold could affect business owners, investment and company transfers. Swiss voters rejected the initiative.
