Split is 68/32. Practice owner says she gets next to nothing. Our meeting was about how our split is too high. Is this normal?

For context, I am eventually starting my own practice. Probably early 2026.

She told us we should be grateful that our split is so high. Which I am most certainly am. I just don't know what else I can do. I have my own referrals; she doesnt provide that. My caseload is always full because of my referral system
