Note, however, that growth depends not only on physical infrastructure but also education systems, health services and environmental care. The outgoing administration's stimulus package of $830 billion during 2009–2019 rightly included transport, energy, social sectors and the environment. But it did not focus sharply on growth impediments. Rather, the rationale has been that, during economic downswings, the government can offset the decrease in private spending with more public spending. This approach helped stave off a depression, but it didn't target growth obstacles like raising worker productivity.
