As someone who has experienced family adversity in my life (health, disability) I couldn’t disagree with you more.
Things happen. Expensive things. The security to be able to afford expansive cancer care without worry, to pay for therapy and specialized schooling for your child… these are huge, huge things and they happen to you (or your children, or your children’s children) no matter what you do or don’t do. This isn’t just about being happy to be frugal.
Things happen, it’s true. And in the world there are many enterprises that spring up to present solutions as long as you fork over all your cash, and here in the USA, based on the market, that means lots and lots of cash.
That’s just a perspective on hardship, it’s not the only way. People deal with hardships with many many tools. My favorite tools are dignity, grace, courage, personal strength, and ingenuity. Money is another tool, yes, but it tends to prevent mastery of the others.
Elsewhere in the comments there was talk about legacy. You can give your kids a bank account, and the examples that you had money to pay off problems. Or you can give them something else through your example. I choose the latter.
