If everyone was rich and wealthy who would make the sandwiches?

So many time the conversation show up about how all the wealth is consolidated at the top by the top 4% of society and their conspiracy to horde it and lock everyone else out. If you took all the billions possessed by these billionaires and multi-millionaires though many would call that socialist, and/or had a way to make everyone near equally wealthy who would make the sandwiches? Who would make the sandwiches be lumberjacks, shoe shiners, pit bosses, correction officer, coal miners and other jobs people have more than likely because they need the job not because they chose it over every other possible job out there if they had the choice to do something else?
