Its very sexy!!
You see instead of working our arses off for Big-Business; in the socialist society, the work needed to sustain the society at a reasonable level would only take, say three days a week. The only reason people work 5 days is to keep the lazy rich in their mansions.
So with all the extra time, we could have lots of free love and stuff. Thats why it is sexy. Everyone on equal terms economically, everyone on equal terms sexually. Lots of sexy fun to be had by all!!!
