Person 2: But what if you're a diabetic blind one legged cancer patient?
Here's my personal experience - I had a single parent who always worked and always had health insurance through her employer. In her 50s she got hurt and couldn't work much (no cobra, no money either) and lost her insurance. She worked in retail for a while. Then she got cancer and died. Maybe if she'd had more frequent checkups it might have been caught earlier? Maybe less stress would have helped? Who knows. I think if we had national health insurance or health insurance you can't lose, then a lot of people wouldn't face this problem, it would help in the aggregate. She never got to 65, so she didn't jump onto the safe medicare.
Whether or not there are improvements to be made to our healthcare system is an entirely different discussion than whether or not an average, able bodied person could reasonably go out on their own without another person working in the home to back them up financially. Of course it would be better/easier to have a support system with another worker in the house. Of course it would be better if you had easier access to healthcare. I would never suggest otherwise.
Also, I'm sorry for your loss. My mother is a cancer survivor and it's just a shit situation all the way through.
Buying your own workman's comp is 0.0075% of your salary in my state ($0.75 per $100 in salary). Disability insurance is $30/mo for $50k salary, so if you're making $30k/yr then disability will be even less. You can make a budget, avoid consumer debt, and save an emergency fund at virtually any level of income. The median national income is $32k/yr for a single person. Sure, a lot of people making that kind of money also have bad personal finance habits. But the idea that it's impossible to live a decent life on the kind of income that half of all single people in the country are making is hyperbole.

One guy is living life probably pulling in upwards of $150,000 a year (or living in a lower cost of living place with six figures income). Simply budgeting well will cover all these things. And another thinks that "budgeting" means you don't get to eat on Mondays so you can keep on bills.
