I think one common theme here is that experience is the best teacher. Some of us lack that experience and may be making poor financial choices as a result. If I knew 30 years ago what I know now I would be a millionaire several times over, barring the a/m medical/insurance problems. The biggest difference for me would be NOT trying to live a lifestyle on the edge of disaster, NOT financing non-essentials (permanent housing and education being the only exceptions) and saving as much as possible for the proverbial rainy day and eventual retirement that I would hopefully attain someday.
It took me the better part of those 30 years to get into debt (happened quickly) then dig myself back out of it. I had a similar situation with a wife with lifelong medical problems (diabetes and the eventual consequences) but fortunately for me a combination of insurance that did not cause any problems and her early qualification for Medicare took care of most of the associated costs including her very expensive dialysis treatments for end-stage renal failure. I was indeed fortunate in that sense and I am ever grateful for my current situation. But I have seen much worse all around me, like jayn_j describes, and I am trying to protect myself accordingly in case my health turns sour. That includes some active lifestyle changes to get myself in better shape (better diet, daily exercise, routine check-ups) and health insurance to match my current situation (high-deductible CDHP with a tax-deductible HSA to cover the deductibles and incidentals, and a $5 mil. lifetime max.).
My recommendation to any who care to hear it is to NOT go into pesonal debt to support an elevated lifestyle. Save like there IS a tomorrow, but one in which you may not have any income for an extended period. When you have amassed a sizeable nestegg, then spend cash (only) on some luxuries. Take care of your own financial situation independently and plan on there being no help from others or the "government" (i.e., We The People). Insure youself well against the unexpected (including umbrella liability insurance). Even folks starting out with nothing can eventually attain sizeable wealth that way. The worst plan killer is poor health - both physical and financial. Everyone has some abiilty to control - and a personal reponsibility for - both types of health.
I follow the Dave Ramsey plan for the most part now, the one where the "status symbol of choice is the paid-off mortgage instead of the BMWs in the driveway". I wish I knew that plan 30 years ago...!
