Pretty much all of that is handled by the social safety that the government is there for or by your own savings that you build up because you are an adult and look ahead to make sure you can deal with such events. One of those things is planning and specifically financial planning.
A full quarter of adults in the US have no savings at all. It can be hard to build up your reserves when more than half the money you make from your two jobs goes to rent. Did I mention those jobs are both "part time" so no benefits either.
