I think he is definitely wrong on the union issue. He's just extrapolating from a limited perspective of, presumably, poor experiences.
Seems like much the same attitude that produced Thatcher's assault on Trade Unions (and it's very clear that abuses did happen, pre-Thatcher, and not at all just in the public sector - I knew people who worked in Fleet Street, and it was astonishing what those unions got away with, even the very-left-wing people I knew were kind of amazed at what went on...the point being it happens in any industry that is not facing severe competition).
But the subsequent loss of union power has produced worse problems than it solved, and if the current government now finishes off the last remnants of union power (concentrated in the state sector or the remaining strategic industries like rail) things will just get even worse. Police unions though are just a terrible idea, and I don't think many other countries even have them in the form they take in the US.
I have no idea about 'zoning', though, we don't even have it over here, instead there's just a rag-tag of local 'planning regulations', that have never been framed in terms of 'zones'.
And those development regulations seem to keep getting alternatively expanded and rolled-back, almost always by the Conservatives, who can't seem to make up their minds what they think about the concept, as that party represents both the NIMBYs and the small business class and landowners who dislike planning constraints.
