The Ares V, using SRB's and the external tank from the shuttle would have been more powerful than the Saturn V. For some inexplicable reason it would have taken 15 years to develop. It's cancelled now.
And the free-market Dragon spacecraft with a capsule capable of carrying 6 humans is working (but it's taking NASA a long time to man-rate it).
Government isn't the solution, unless you need lots of dead people. Governments are good at that.
