I can't stand Donald Trump but I think he has the wherewithal from a personality standpoint to rebuild, financially he may need partners.
The Freedom Tower is disgusting in the shadow of was once there. It just doesn't compare. The WTC was something bold and majestic and built during a decade when bold and majestic things in this country were not in vogue.
The memorial on that link someone provided is better than any I've seen. I love the idea of the rebuiling and putting up the remaining walls of the original as a surrounding feature of the memorial.
I think that construction should have began 2+ years ago on something. The fact that this is still an empty pit should be an embarassment to the country, state and city.
