Wouldn't it be more rational to pay the tax than to buy insurance?
No. Paying the tax is the irrational choice. In exchange for paying the tax, which will eventually rise to 2.5% of your yearly income, you literally get nothing. When you pay for insurance, which will come with a check from the feds to help you afford it, you get something. Something is better than nothing, you see.
A 29-year-old in California with an income of $25,000 has two options:
Pay a $52 monthly tax to get $0 worth of coverage.
Pay $144 monthly for insurance to get $229 worth of coverage.
Wouldn't the rational person just pay the extra $92 a month for health insurance? Even if it's a "bad deal" at the $229 level, it's certainly worth it at $144.
If you are in catastrophic accident, it won't matter whether you have insurance. And if you develop a chronic condition, you can buy insurance.
Without insurance, many chronic conditions will go undiagnosed long enough to cause serious adverse health effects. Passing on insurance rules out some very basic screenings that could literally cost a 29-year-old his testicles to cancer. Or a woman at risk of early breast cancer. These things happen, and without insurance, they destroy. Lack of access to healthcare also increases costs of obtaining doctor services when needed, leaving people hesitant to call an ambulance at the first signs of a heart attack. It also increases the costs of prescription drugs, which encourages the mentally ill to skip their meds. Do you know what CVS charges without insurance? I mean, good lord.
Catastrophic accidents, meanwhile, will ruin you financially. If someone is poor enough to skip on health care, they're poor enough to be destroyed by a single medical bill. And if the poor are getting "free" care now anyway, who do you think is paying for that "free"? It's you, your insurance company, and the federal government. Society pays no matter what, so why does it matter if it takes the form of ObamaCare? Do you think poor people are going to be wrongly encouraged to get more sick than otherwise?
I don't see how the Dems can successfully make the argument that healthy people have to subsidize unhealthy people.
That is literally what health insurance is.
