You also probably don't have to worry about getting sick or injured (health insurance and sick leave are basically assumed in most careers that pay >$100k/year), getting access to money (whether savings or credit) for emergencies, or being able to support a loved one when they have problems.
There's nothing "glamorous" about scraping by month to month, working an hourly job with no benefits or paid leave, or having to lie to get access to social services to support your family. It might not be as bad as living in medieval-era poverty, but it's still miles away from your six-figure professional lifestyle.
Life can be (and often is!) fine day-to-day when you're poor, but the complete lack of an effective safety net means the difference between "doing okay" and "living on the street with no options" is razor-thin.
