They aren't choosing to have crap infrastructure, their infrastructure is intentionally defunded as part of a political campaign to engender distrust in government functions and increase privatization. Government is incompetent because if it is, its easy to justify selling off the country to the incredibly wealthy so they can get wealthier.
It's a bit worse than that. The infrastructure isn't actually defunded, there are huge funds allocated to projects, but they're being consumed by managers at Deloitte, Lockheed, Booz Allen, Accenture, etc. The times when we see success is when enough funding trickled down to the few engineers who could make it work with what they get. Other times we see success is when there is enough public oversight by sufficiently independent stake holders. I see this in many local government agencies that are small, and projects accountable to city council, and so on.
