> The difference is that we've more or less hit a stable Pareto front in education and healthcare. Gains are small and incremental;

You probably mean gains between someone receiving healtcare and education now, as compared to 10 years ago, or maybe you mean year to year average across every man alive.

You certainly do not mean that person receiving appropriate healthcare is only 2% better off than one not receiving it, or educated person is noly 2% better of than an uneducated one?

Because I find such notion highly unlikely. So, here you have vast amounts of people you can mine for productivity increase, simply by providing things that exist already and are available in unlimited supply to anyone who can produce money at will. Instead, let's build warehouses and fill them with obsolete tech, power it all up using tiny Sun and .. what exactly?

This seems like a thinly disguised act of an obsessed person that will stop at nothing to satisfy their fantasies.
