Perhaps some millionaires & billionaires, or some huge multi-national corporations, will come to the rescue, but most likely they won't. During the New Deal era, however, this would have been the type of job that the WPA would have routinely engaged in. The WPA was prolific at constructing new schools--5,908 of them--and even more prolific at repairing or improving schools, performing over 30,000 such projects.
Recall that the community around the damaged school raised $200,000. During the Depression, the WPA usually required that local communities raise a certain portion of the money needed before they would kick in the rest. In this case, the $200,000 would have been more than enough for the WPA to fill in the gap with the remaining $700,000.
And if you're wondering about the quality of work performed by the WPA, you can find thousands of still-existing WPA projects on the map of the Living New Deal--an effort that has only just begun to highlight the New Deal projects that we still enjoy & utilize today (WPA, PWA, CCC, NYA, etc.).
Isn't it a shame that we don't have a WPA today? The politics & principles of the New Deal, based on hope and optimism, have been replaced with a political cynicism that lets our infrastructure deteriorate and causes public officials to insult the less fortunate, for example, when a Republican school official in Arizona called low-income Americans "lazy pigs" and when a Republican Lt. Governor in South Carolina advised us not to feed low-income school children because they might breed.
We need a new, and even stronger New Deal. Unfortunately, all we're likely to get are deteriorating schools and continued political scorn for the less fortunate.
