Technology alone doesn't do the trick, the change of preferences is at least as important.
The replicator only makes the production of food, clothes and other ordinary goods cheap.
You say that like it's nothing. Now, obviously, there would be a cost to the replicators themselves -- but once you have working replicators, you essentially make all these other resources so cheap that they might as well be free. That's huge. It renders a predominently Capitalistic economy impossible.
It doesn't solve land scarcity and it doesn't address any labour market issues.
Well, it renders vast amounts of labor unnecessary, since it's suddenly no longer necessary to expend labor to obtain uncountable numbers of goods.
Let's use the ugly word, 24th century humankind is a socialist society
Well of course it is -- for the most part. But that doesn't mean some small private markets don't exist within the larger socialist system. For instance, it's pretty clear that everyone eats just fine, but I do suspect people pay to go to restaurants. If only because I have yet to see a restaurant where the waiters would be willing to do the work for no compensation.
Incidentally the most socialist systems (relatively, they are of course mixed, social democratic and not socialist economies) in our world, the Scandinavian ones, do extremely well if you measure doing well by GDP, income equality or constructed indices that take into factors like health, crime, pollution and so on that are not or imperfectly measured by GDP.
Yep!
