Perhaps the most common question I’m asked about ObamaCare is: “Will I be able to buy my way out of it?” The answer is: “Not unless you’re very rich.” The plan before the Senate creates a set of 50 state-based insurance “exchanges” that are established as markets for health plans. Consumers must buy policies from their employers or through the exchanges — but, either way, their choice of coverage is limited to one of four basic insurance plans that the government sanctions.
