Nah, it takes a lot of attention to keep $10 million under control. Unless you want to risk running out suddenly.

Having $10 mil in a bank account somewhere is pointless. No matter what philosophy you want to apply choices must be made. Investment, consumption or hedonism. The money will quickly vanish (decade or two) if the balance is wrong or the millionaire goes all-in on indexing at the peak of some bubble.

Investment, consumption, and hedonism: unless you have a broad sense of “investment”, aren’t all of those selfish?

I suppose my valuing the health of an ecosystem of other lives is selfish, too. I’m writing to push for a broader sense of what it means to invest, as in increasing the carbon content of soil for the health of future life, and promoting regulation towards cleaner air and water.

Giving money away to worthy causes is pretty easy. But FYI I'd class that under my broad definition of hedonism. In Xanadu did Kubla Khan .... and all that.

So that your escape money doesn’t get eaten away by inflation. You could put it in a low-ish risk portfolio composed of some bonds, indexes, etc so that it continues to make some amount of money.

Taxes and inflation will kill you.
