I'm actually surprised things haven't gotten cheaper by more than a factor of 5 in half a century.
We're used to electronics getting cheaper as we find ways to make smaller and faster chips. We get change driven by Moore's law.
Getting to orbit is governed by simple lifting against gravity, and that hasn't changed at all. ( It's still 9.8 m/s^2 ) A Falcon rocket looks a lot like a Saturn rocket, so desipite a lot of ideas, a radically different and better design hasn't been commericialised yet.
