It is not fair to compare the heavy lift capabilities of the Dragon to those of the space shuttle. The fact that the Space Shuttle does both heavy lift and crew transport means that whenever you want one, you also have to pay for the other. Of course you would not use the Dragon to launch the Hubble.
A fair comparison would be 1 Dragon launch and 1 Falcon Heavy launch which leave quite a bit of room for cost overruns before they surpass the cost of a shuttle launch while delivering twice the payload and the same number of people.
Lastly the total cost of the Space Shuttle program divided by number of launches gives us a cost of $1.5 billion per launch (2008 dollars), according to Wikipedia. While NASA lists the launch cost as $450 million, that does not include the majority of the cost of the program. NASA paid a comparatively small sum ($270 million) for SpaceX to develop the Dragon (Even if there was a second contract that I am unaware of, the cost still cannot approach that of the Space Shuttle).
