I get your point but people with high income are paying proportionately more than people with lower income. In some sense this is a subsidy. This becomes even more pronounced if you take into account who is using the health care system as low income tends to be tied with bad health (diabetes, smoking related issues, hard physical labour, etc). Note that I'm not saying this is wrong. Broadest shoulders should bear the largest burdens.
