Straw man argument. From the onset of your argument you base it off an inheritance. Whereas if one is elected to office one has to chose to run. Knowing that being an elected official is limited in time, the hope is that those choosing to run have a higher purpose then wealth accumulation. Your proposed assumption is that the sole reason for office is gathering wealth. My other proposition is that under the current laws, US lawmakers do not face term limits and they all seem to end up becoming millionaires in the process of legislating. Something seems amiss to me.
