First, DailyMail, F off.
Anyway, for context:
My DH's family is upper middle class, but the parents came from rich families. But my DH and his siblings were sent to exclusive schools, went to good universities, etc.
My FIL's earnings were probably dwindling and just enough to support the family, but not the lifestyle my inlaws were used to. My DH has been working for 20 years before we got married. For all those years, all his money went to his family, I guess to supplement so that they can still enjoy the same lifestyle. He was conditioned that to be a good son, he needed to do that and he felt guilty whenever he wanted money or anything for himself.
My DH has always had a good job. Even starting a company right out of the university, which was acquired by a bigger company hence there was a big payout which, you guessed it, went to my inlaws. My DH and SIL have a big age gap, so at that time, she was just growing up/in school.
Few years before we got married, my FIL's business did really badly and accumulated a lot of debt (this is according to the MIL, so her contribution in the debt was probably downplayed). But I know that my MIL also dabbled in some ventures that failed.
My inlaws then sold a property and suddenly had money again.
My DH cut his support to them since they have money already. And my DH does not have any savings for himself so he was starting from scratch at 40, despite having been a high-earner for most of his life.
My inlaws told my DH that they will grant access to the money to my SIL, if that's ok with my DH. He was fine with it.
My SIL then started investing in some companies and bought a fancy car, presumably from the money that my inlaws got from the sale of the property. Still fine with it as it's their money and they can do whatever they want with it.
Now my inlaws still have money - enough to last them for maybe 10 more years if they will continue spending like they're spending now.
My SIL started working for a company, but still maintaining her investments. According to inlaws, it was because the investments weren't really generating money. Whenever I talk to the SIL, she's always mentioning her investments, and how she has two international trips already planned for next year.
She is now suggesting that they (the children) start an emergency medical fund for the parents, which is a good idea, except she wants it done by percentage of salary. Clearly, she knows that my DH has the biggest salary out of all of them. The other sibling does not even have a regular job! So essentially, it will be my DH mostly who will be contributing to the fund.
AIBU to think this is not a fair idea?
