The Affordable Care Act was passed by a Democratic Congress in 2010 with no Republican support. It expands access to healthcare but does nothing to control costs which have now reached 18% of GDP and climbing.
The current Republican Senate bill to replace the ACA does attempt to control costs but is unable to attract enough support to pass.
The problem is to achieve both broad access and much lower costs at the same time. In general, Democrats prefer a single payer system while Republicans want to retain a free market approach. So compromise will be required.
- The tax exemption for employer provided health insurance should be replaced by a universal (and refundable) tax credit for all limited to the cost of catastrophic health insurance (with a high deductible). This will preserve expanded access as well as requiring everyone to pay attention to costs.
- Tax preferred health savings accounts for routine healthcare expenses should be authorized and further subsidized for low-income families through the ACA exchanges.
- Medicaid (for poverty-level families) should be put on a fixed federal budget to control runaway costs. States should be given much greater flexibility to direct resources to those with the greatest needs.
- Redesign of Medicare. Medicare is currently being subsidized by the federal government (after FICA taxes and premiums paid) at over $400 billion per year. Introducing a defined contribution element into this single payer program will help to hold down costs.
- Pre-existing Conditions can be covered with suitable enrollment windows and state-run high-risk pools.
Conclusion. The ACA has achieved nearly universal access to healthcare in the U.S. But costs continue to rise sharply. A universal tax credit combined with health savings accounts for the private market combined with a defined contribution single payer Medicare system has a good chance of getting overall healthcare costs under much better control.
