The third policy debate involves how to equitably impose insurance premiums on the workforce throughout the nation. Korean workers are represented by 2 different labor organizations, which take opposite positions in this debate. The Korean Confederation of Trade Unions, representing the progressive wing of the labor movement, is strongly opposed to decentralization. The Federation of Korean Trade Unions endorses decentralization, declaring that the insurance premiums paid by employees should not be pooled (centralized) with the insurance premiums paid by the self-employed. The Federation of Korean Trade Unions argues that an equitable health insurance premium "tax" on all workers is impossible because 53% of the self-employed do not pay any income tax.
