I respectfully disagree. We need a society of people who hate working hard but, very importantly, are deeply empathic so they won't just leave the hard work for other people. Those are the people who automate the hard things away and share their work so other people can do the same, to leave time for science, abstract creative pursuits, recreation, etc.

Yes, we definitely need more mindless wage slaves and worker drones who like being used and exploited.

I think we need people who have more empathy for others, have more patience, have more respect for fellow humans, animals and the environment in general. I feel working hard, intelligence etc are secondary to empathy.

And what will they do, when robots take all their jobs in some time?

this is highly subjective topic, nobody really knows what mankind truly needs long term in current state. we can state our own personal preferences that would improve things we care for, but that's another topic with possibly different outcomes.

For example, I can easily say we need more people with high moral standards who don't lie, cheat partners, friends,family and do overall positive added value to mankind. This can be anything from freeing a seat in full bus to granny/pregnant woman to curing some specific type of cancer, and anything in between. They don't even need to work hard on this, even small positive action here and there, multiplied by 7 billions, would change our lives gradually for the better. But that's just my subjective 2 cents :)

>normal-intelligence humans who like working hard

Because working hard is a virtue, right?
