Just another success of the tax reform. It's almost like letting companies keep more of their own money allows them to actually use that money towards productive ends in the economy. Gee, how strange... 
Not more iPhones.
That you can't see or understand this exposes a major problem with your logic systems.
America
does need those things, but it's not Apple's job to provide them. However, with Apple bringing in their overseas money and paying taxes on said money ($38 billion, according to the article) AND creating new jobs (those workers will now be paying taxes too), more money will be going to the government to fund those projects you speak of. The economy is not some zero sum game, where if Apple increases supply of iPhones, money has to be taken away from somewhere else; new wealth is being created in this situation, not being diverted away from public projects towards iPhones, as you suggest.
