In some European countries (probably not Poland) the unemployment you get for about 2 years if you lose your job is sufficient to cover a mortgage. The philosophy is that it is cheaper for the state to help people stay in their existing home than to have them lose it and potentially have to house them and them never go back to being a net contributor.
All states in the United States have unemployment assistance programs, as well as programs like Medicaid to provide health care to the poor. OP's dad is nearing retirement age and can probably take advantage of some state-provided retirement benefits, like social security and/or Medicare.
While things may be less extreme here than in Europe, you aren't just left to die if you become unemployed. Government-provided insurance that you have to be either poor or old enough to get is actually much better than a lot of the private insurance plans that are the only option for the middle class.
