Why are some wealthy people so frugal?

Because wealth and frugality are related. You can become wealthy in very few general ways:

You can inherit;

You can invent something that people want to buy;

You can be amongst the most hard working, capable and talented at something people will pay for;

You can rent seek (use connections to take from others that which you do not deserve), or;
You can save and invest (live below your means).

As you can see, most of that list is not available to most people. One item, #5, is generally
available (this may be a bit of a USA truth, I cannot speak to other countries).

Bonus, if you live your life according to #5, then your children have a chance for #1.

Rich people bear the risks along, and they suffer losses alone. So no-one should tell them how to spend their money if they strike it rich.

Men are stingy because women these days are not worth spending on.
Before women were like butterflies, beautiful, flamboyant and hard to catch, now they're annoying loud and easy to smash.
