Would you donate your money if you’re classed as ‘rich’?

[Familylifeof3]

Hello,
A bit of background - I’m 33 and my husband is 34, we have 2 children who are 7 and 3.
We live around Cambridge and my husband commutes to London every day for work. He works every weekday and sometimes weekends too. He often flies over to America for work. He works extremely hard and does earn a lot of money.
We live in a relatively big house and have 2 lovely cars. I don’t have to ever worry about money and our eldest goes to private school (youngest will too when old enough).
We live a very lovely life and we are so grateful and take nothing for granted. I grew up with parents on benefits who struggled to afford bread most weeks and went to a pretty bad school in a pretty bad area so totally understand what it’s like to be in that position.
I work for the NHS (always have and always will) as I love caring for people.
Recently my husband got a promotion so we would love to donate some of that money to the NHS. Working through covid I am so aware of the struggles and want to support this the best I can.
I really feel they would benefit from a bit of money. And as I grew up with parents who struggled to afford the basics I really want to make sure people get the same care wether that’s privately or through NHS. I don’t feel money should make a difference in that.
Anyway, I told my sister and she looked horrified and said that we shouldn’t ‘waste’ money and should by a holiday house and yacht in America instead of donate.
I hate this idea and absolutely do not agree with that approach. She said we’re being selfish by not offering our children the best start in life!
Just to add my sister has always been a bit jealous of me and has always been funny about how we spend our money (wants to live through us sort of thing).
So do u agree with my sister? Or do u think I’m being totally reasonable in donating most of it?
TIA xx

That's is true. Yes.

But they're living in deprivation... And they can live wherever they choose, surely?

I know that, I'm not stupid. Nor do I plan to send mine to private school. If you need me to be specific re the OP's other mentioned financial commitments, I would be annoyed with myself if I were made redundant 6 months after donating a large amount, with a big mortgage to pay on a "large" house, and a smaller audience to sell it to if needed in a recession. I would be keeping the money for a few months to see how my job security pans out. Happy to be called hypothetically "narrow and selfish".

In the last 2 days?

Yeah probably.

Which is why I suggested regularly donating to charity, but the OP seemed to be suggesting giving away a huge portion of her and her DH's income, which with his one salary supporting them all, a huge cost of living increase and a probably looming recession, would be completely irresponsible. What if he loses his job and suddenly they've got no money? It happens. People who don't save for a rainy day when they're earning well can end up having to pull their kids out of schools where they're happy and settled and even losing their homes.
