Possibly the biggest driver of sickness in the US is stress, and also lack of hope which is a driver of depression. The best way to get a future is to think about the future you want and spread the idea and join a movement to work toward that future. The exact opposite is the direction we are heading in right now, with the Biden Administration and the Neo-cons. And the present crop of wars is just what happened with G W Bush and the Neo-cons running G W B's first term in office.
Who can survive the stress of getting sick? How much will the health insurance pay, and for what? A friends sister got sick, needed a liver transplant, and the heal insurance paid up to the max, leaving her a bill of around one million dollars. If she could pay off 3,000 a year she'd clear that bill in just 330 years.
I went off topic. The HOPE is that because it costs less to run a single payer healthcare system, that we will dump the patchwork quilt system we have for something simpler. That would save money so we'd have more money to spend on wars, which is the government's main objective.
