5 Developed Countries without Minimum Wages
Sweden, Denmark, Norway, Iceland, Switzerland.
CAVEAT:
Switzerland saw a proposal for a legally enforced minimum wage soundly rejected in 2014. The decisive vote against a $25 per hour base salary was touted as evidence the Swiss do not want or need government intervention, which might cause low-wage workers to lose jobs if employers are unable to pay more. However, like all the countries listed in this article, Switzerland relies heavily on trade unions and employee organizations to negotiate fair wages for each industry, meaning 90% of the Swiss earn more than the proposed minimum anyway.
I would also add — SINGAPORE also has no minimum wage.
Are you sure about Denmark? I know a guy who lived there for a time and he told me their minimum wage was $25/hr. For whatever reason eating out there was horrifyingly expensive.
