Everything you own is bought with the same thing. Your ability to work.
People insure the house, the cars, the boat and the dog, and leave uninsured the single asset that pays for all of them. A working person in their thirties will earn more over a career than the value of every physical thing they will ever own, and that earning capacity is far more likely to be interrupted than the house is to burn down.
Disability is not mostly about dramatic accidents either. The common causes are ordinary and unglamorous: back and joint problems, cancer, heart conditions, and mental health. Things that do not make a good story and still stop the paycheck for months or years.
The Pennsylvania piece matters here. Some states run a mandatory temporary disability program, and New Jersey is one of them. Pennsylvania is not. A Pennsylvania worker who cannot work has whatever their employer voluntarily provides, whatever they bought themselves, and eventually Social Security Disability, which is difficult to qualify for and modest when it arrives. Because we are licensed in both states, this is a distinction we end up explaining often, particularly to households where one spouse works across the river.
Long-term care is the other half and a different problem. It is not medical treatment, it is help with daily living, and health insurance and Medicare cover very little of it. The default plan for most families is to spend savings until Medicaid takes over, which works, in the sense that it produces care, and destroys what was going to be left for a spouse or children.
Pennsylvania offers a genuine middle path through its Long-Term Care Partnership Program, which lets a qualifying policy protect assets dollar for dollar. It is one of the better-designed programs in insurance and one of the least known.
