My parents have recently told me they are going to leave their entire estate to my brother. So, he is getting a two-bedroom apartment in the capital and whatever will be left of my parents' savings, while I am getting nothing.
Their explanation is that my brother is very unlikely to build a successful career. He has failed to graduate from his university and has a number of personality issues. Unless a miracle happens, he'll always be working low-skilled jobs at best. In contrast, I have graduated from a top university and have started a career abroad, so my parents believe I am in a perfect position to meet whatever financial needs I may have in the future. And if I don't, it will be all my fault, they say.
Asked why they were telling me this, my parents said they wanted to ensure that I take responsible financial and life decisions and don't count on any possible inheritance.
Their decision feels very unfair because my brother isn't disabled in any way. My view is that he is just lacking self-discipline, unable to find any motivation to do anything, unable to plan things, and unwilling to leave the comfort zone.
Question: Is there any good strategy to try to change my parents' mind?
Additional details:
My brother has always been the golden child and emotionally merged with the parents, while I have gradually become emotionally separated from them and focused on my own life. I find my parents toxic and manipulative and enforce boundaries to protect myself, while my brother gets along with them just fine. He is highly manipulative himself and emotionally dominates them.
My parents believe that the key to earning good money is being gifted rather than hard work. And they say it's not my brother's fault that he isn't as gifted as they believe I am.
My parents and brother live in the same city, and I'm afraid my parents might see their estate as a means of ensuring that my brother feels obligated to provide them emotional and organizational support should they need any help as they age.
Here are the arguments that have come to my mind so far:
Their decision is very unfair, because the parents are essentially punishing me for my hard work.
My brother doesn't need the entire estate. A half of it would be enough to buy him a home, albeit not as large and not in such a location.
Because of the utter unfairness of their decision, I can't really continue having a normal relationship with my parents and will possibly severe it at some point in order to get my peace of mind back. The thing is that any contact with my parents will remind me about their unfair decision, so I'll have to significantly reduce my interaction with them. And the same goes for my relationship with my brother.
If my parents gift their entire estate to my brother and then turn to me for any significant help, I'll face a difficult choice and I don't know what decision I will take. On the one hand, they are my parents, but on the other hand, they currently have enough estate to meet any financial needs they may have in the future. They have a lot of savings, and they can downsize their home if needed. So, if they give all they have to my brother and then ask me to invest my money, time, and effort to help them with anything, I will probably refuse.
