True family would support you leaving them to find a better life. They'd be sad but happy for you. Happens every day all over the world in all families.

Is it ableist, yep probably. And it sucks, but if you have the means, use it. Don't waste the opportunity. Build the networks, make a life elsewhere and then get your family out to join you. Why do you think families pool their resources to send their fittest, youngest and most economically likely to succeed across borders or on boats to Europe, or walking to the US for example. The "where are the families of this isn't an invasion" crowd are either stupid or purposely dog whistling when they say this btw.
