If we buy Haiti a bunch of food and deliver it, we have created the jobs and infrastructure to solve the issue precisely in the manner you describe.

We've created an import market, which is good for folks who aren't Haitian who are shipping to the island.

But we haven't created points on the island to receive the new cargo (their port system is in shambles) or distribute it (roads still wrecked from the earthquake, very few warehouses or retail facilities to distribute to local populations) or use it (no reliable electricity or housing).

You seem to take issue with the idea that the solution did not arise from capitalist market forces.

Just the opposite. I believe capitalist market forces are a big reason why Haiti remains poor. Keeping the majority of the population clustered along the coast and forced to compete for sweatshop jobs at the lowest conceivable bidding rate means foreign firms have monopolized the labor capacity of the island while denying them the ability to develop their own domestic capital (roads, power, housing, etc).

Getting construction materials to the island, along with skilled engineers to both rebuild shattered infrastructure and train up locals to maintain/expand on what was built, is the only real path to prosperity. And its denied to the Haitian people deliberately, in order to keep them subservient and to enrich the folks exporting their labor product off the island for pennies on the dollar.
