Dear Liz: You usually don’t give me such a laugh, but today’s letter was from someone who’s 41 and her husband is 51. They now have $800,000 saved and want to retire early. You told them they might do better leaving the country since it will be so bad for them with health insurance.

My husband was a teacher in Los Angeles, with no Social Security. We have $60,000 in the bank and together we bring in $3,400 a month. We have Kaiser insurance that totals $2,400 a year for both. We have a house, a car, not so much money, but are happy. He’s 82, I’m 79. What planet do you live on? I guess people who have so much money can’t imagine people like us.

Answer: You’re living on Planet Medicare, so perhaps you can’t imagine what people are facing who don’t have access to guaranteed medical coverage.

Currently, those without employer-provided insurance can buy coverage on Affordable Care Act exchanges, but that option may soon be going away. Congress ended the ACA’s individual mandate, which requires most people to have insurance, so costs are expected to rise sharply.

In addition, the future of so-called “guaranteed issue” is in doubt. The ACA currently requires health insurers to accept people with preexisting conditions and limits how much people can be charged, something known as “community rating.” The U.S. Department of Justice recently announced it would not defend those provisions against a lawsuit filed by several states.

When health insurance is unavailable or unaffordable, it doesn’t matter if you have $1 million or more in savings. A hefty retirement fund can disappear in a few months without coverage.
