Have never dug into it all but some of HG Wells’ politics have seemed globalist utopian.
He was a Communist. Even mentioned it a bit in “The Time Machine” of wanting to see what a future Socialist/Marxist society of “equality” would look like (they took all that out in the film adaptations). We know now what it does look like in practice: totalitarianism, no electric power, and human $hit on the sidewalks and streets.
Well... he was a Fabian socialist, albeit briefly, as I recall he thought of them as slackers.
