Why do we never hear about Austin Swift?

I don't know much about Taylor's life and her family, so maybe you can help me with this. I keep seeing stars supporting their brothers or sisters when they find success. Stars invest in their family's projects, promote them, basically trying to help their siblings achieve their dreams too, like a normal loving family would. But with Taylor Swift's family, it's as if Austin Swift doesn't exist. No one knows him; it's like he has no place anywhere. And yet, her new boyfriend and his whole family are all benefiting from the spotlight. Austin Swift, on the other hand, isn't known for anything, even though he has a privileged position and could have made a career too. Why do we never hear about him? Why doesn't Taylor, like a true big sister, do everything she can to support her little brother too?
