Tom,
That is not my experience at all. My take-home is much higher in my solo practice than it ever was in a group. I think the distinction is "group" vs "hospital-owned, employed physicians". When the hospital owns the group, it can charge both a "professional component" and a "facility fee", then share part of the total largess with their employee docs, resulting in higher income. Remember, no one is ever going to pay you more money than you can generate. Either you make more money by the sweat of your own brow, or by forfeiting your independence and control over your destiny. As a solo doc, I know how to increase my income. I just need to decide if I want to trade more time for money. But, I have that option. Employees do not.
