Many are usually enslaved so that a few can live very well. But when capitalism is balanced in just the right way with socialism only a few need be enslaved so that many can live pretty darn well.
If you have ever had the pleasure of working in a meat packing plant that will destroy your joints in only two years time under the cold, damp conditions and speed of processing, you get to know what enslavement feels like, or spent twelve hours out in the blazing hot sun picking tomatoes day after day you gets a good taste of the not so glamours end of capitalism. And perhaps being a burger flipper at 70 ain’t so great either.
