Both of your Doctor friends are going to lose a substantial amount of their income in the next 10 years. The federal government will be drastically restructuring the medical system as a way to reduce future medicaid payments (which they are unable to fiscally afford).
What's going to happen is More Successful Doctor/Businessman is going to retain his position because he's paid by wealthy people.
Less Successful Doctor is going to suffer the loss of income, sliding further away from More Successful Doctor because he's paid by Medicare/Medicaid/Private Insurance.
