Hopefully we see a sliding scale subsidy system based on market rates for all, including across age and gender groups, with greater transparency in medical billing. The desperately poor can be covered under Medicaid - we're Republicans, not monsters.
So you mean keep Obamacare?
Uh... Obamacare has price control provisions that attempt to force young people and men to subsidize women and the elderly (which have failed), among many other disastrous regulations like the supposedly popular but stupid 26-year old rule and pre-existing conditions rule. I would prefer to see no subsidy, but I'm trying to be politically realistic. We also need to stop endlessly blaming everything on the insurance and pharmaceutical industries and start getting tough with healthcare providers. Lack of transparency is what allows healthcare providers to hide behind insurance companies, and the more layers of government and bureaucracy we add, the further from a truly free and transparent market we get.
Consumers (i.e. the market) are a far more powerful and effective force in changing the behavior of businesses than government could ever hope to be. The government's role should be to reduce the information asymmetry that currently exists with the opaque nature of healthcare spending in the US and allow the market to do its work.
