The buildings that were destroyed when the earth shook were clumsy structures - but they had basic sanitation, toilets and sinks, drainage.
The slums that are replacing them have nothing. Their dirt alleys are narrow and crowded.
One month on there is a key question.
Now that the emergency is over, now that the survivors have been pulled from the rubble, now that most of the injured are getting the treatment they need, now that food and water are getting in through the port: what next?
It is a huge and pressing issue.
For decades Haiti has been dependent on outside help and money.
An estimated 60% of its government budget comes from foreign aid.
Most individuals here survive thanks to the money sent to them by relatives living overseas.
It would be relatively easy, given the money raised, to re-build the presidential palace, the government ministries, La Grande Rue - the commercial heart of Haiti - its Wall Street, if you like.
These are all important things to accomplish. They will be the foundations of the new Haiti.
How though to create a new city, and country, which in the longer term can support itself?
As US Ambassador Lucke put it: "So much of the china is literally broken in this country that there is a chance to put it back in a different way and we hope in a better way."
Only though with a sustained, years-long commitment from the international community will that happen.
And without it, Haiti will simply be another disaster waiting to happen.
