Making inequality comparisons between countries is difficult.

It’s easy to reach inaccurate conclusions when comparing inequality levels among Western nations, given their different labor classifications, taxes and redistribution policies. Governments achieve fiscal redistribution through taxes, transfers for social benefits, and costs subsidizing education and health care. For example, in France, employers pay relatively high social charges for their employees, in contrast to Denmark, where there are no payroll taxes on employers.
