Not when their riches come at the expense of everyone else.
For instance the Walton family who occupy 6 of 10 slots on the richest americans list benefits from an estimated $15 Billion ( with a B ) a YEAR ( every year ) subsidy from the taxpayers to support their employees who could not survive ( as in feed their families ) without supplemental food assistance; not to mention medicare, disability etc. Not to mention the fact that the company they control got to be such a wealth production engine by arbitraging it's way around labor and environmental protections by exporting it's externalities to unregulated emerging economies.
All the people who got pushed into extremely bad mortgages and then lost their jobs because the economy crashed; they were stolen from by Rich People.
All the people who've had their lives destroyed by the financial shenanigans distorting our healthcare system were stolen from by Rich People.
I don't know about you, but given the trail of destruction left behind by rich people in the past 5 years alone; we should be handing them a bill, or showing them the door.
Now, I'm sure many rich people are very nice if you know them socially; but as a class, they're killing this country and this planet.
