What might max weber suggest is the primary difference between a lawyer in the united states and the self-made millionaire of a u. s.-based manufacturing company?

Wealth, power, and prestige--these three elements make up Weber's theory of social class.

In the case above, both have power over others, but their wealth is likely different as the self-made man is a millionaire and lawyers don't typically make that much. The biggest difference would likely be the level of prestige or respect each would get from others. The US values the self-made man over a lawyer.
