Given his personality and his background in development, it only stands to reason that Trump would support a huuuuuge infrastructure spending program. Since private sector investors obviously will insist on the creation of a substantial revenue stream, however, Trump’s plan to use public/private partnerships in lieu of public money means that either: (a) there will be no funds to improve public facilities that are in dire condition, but which do not currently generate revenue; or (b) public facilities that are owned by entities other than the federal government–the vast majority of them–will have to be completely or partially privatized.
The latter approach sounds like something that would appeal to a Russian oligarch. Given Trump’s enthusiasm for Putin and Russia in general, maybe that makes sense.
