For starters, vote Republican. Any liberal selling universal health care is just dumb and dangerous. As heartless as it sounds, universal nationalized care will create disincentives to healthy living because most folks will just continue overeating, smoking, drinking and just assume that a pill will take care of things when they start to feel bad. After all, those doctor visits and the prescriptions will be free from Uncle Sam. Many morbidly obese people are also notorious hypochondriacs (But I have a condition! I have depression / body dysmorphic / ADHD / social anxiety / misc. disorder and the only thing that works is comfort foods. I can't help myself.) and that will clog up clinics and doctor's offices keeping truly sick people from getting in.
The tax rates required to fund universal care will kill our economy and standards of living.
Employers should mandate annual physicals to qualify for health care. Set a mean standard of overall fitness, then determine company / employee premium contributions accordingly. The less fit pay more from their pocket, more fit people get a larger employer contribution. This would benefit the employee as better compensation and the employer gets better productivity from this individual. Healthier people who exercise and abstain from smoking are statistically proven to miss less work and are more productive at their jobs.
