There are lots of spacecraft being built, they just aren't all human rated at the moment. I should mention that I'm including first stages here too because my point is that we have to build the stuff to work the organizational muscles so that we can build more similar stuff which is better performing later.
Rocket lab is launching electron a bunch, working on Neutron which will be a falcon 9 competitor, and is building spacecraft for their customers (e.g. they built some Martian orbiters that should get launched later this year).
Intuitive machines, the folks who built the most recent US lunar lander.
Blue origin is not exactly speedy, but they do fly their rockets semi-regularly now and New Glenn is supposed to fly later this year.
Northrup has a human-rated rocket that flies periodically.
And of course there's ULA.
And those are just the successful ones.
There's also:
Astra
ABL
Firefly
Relativity
Sierra Space
And probably some more that I'm not aware of.
That's a pretty long list of places that are working on these problems and paying American engineers to work on and think about these problems.
