Well, neoliberalism happened.
You see, space exploration, at least in the stage in which we are now, isn't bound to yield any significant profits or returns, at least not within lifetimes of people investing into it today.
Its literally something, the fruits of which will only be seen by our grandchildren, if that.
And that's why post-cold war Western space program became a faint shadow of itself - West is ruled by cosmopolitan oligarchs, greedy and ignorant types that don't care about what happens in the future after they are dead.
In comparison, Romans would plant trees that they would know would only grow many years into the future, way after they are gone. It took multiple generations of people to build those legendary medieval cathedrals, people that begun construction new full well that the building won't be finished until after they are long gone.
Unfortunately the inferior (to their predecessors from middle ages and antiquity) elites we currently have don't have such mindset, which is why the elite-approved take is how space exploration is "stupid and expensive". And to a materialist person without some kind of higher ideal it is.
