What's historically speaking the "standard technique of privatisation"?
Assuming that there was indeed some standard technique, then I'd look what was the biggest privatisation program in history - economic transformation of the Eastern Block around year 1989.
Were the enterprises in awful state as described Chomsky? Maybe not technically speaking defunded, but still close enough.
Were the enterprises sold in haste, often in questionable manner (especially Russia or Ukraine)? Yes, in a way that would make Chomsky blush.
Nevertheless, assuming that there was some sinister conspiracy behind, then such activities were done by communist parties... OK, by well placed capitalists agents spread all around such parties who launched a coordinated attack in late '80s. Hmm... we reached even beyond an Alex Jones conspiracy level to justify Chomsky claim, so let's think about a bit an alternative explanation.
Let's think for a few seconds which issues government owned enterprises may have:
- political appointees to run them
- often are ordered by politicians to do activities that are questionable from business perspective but are good from perspective of politicians reelection prospect
- tend to operate in markets with limited competition or are too big to fail (private owned enterprises in such situation start to behave in pathological way...)
- instead of being supervised by potentially furious and nearby shareholders, they tend be supervised by much more distant and less informed voters.
Let's think in which situation politicians (except some free market fundamentalists) start openly talking about giving up a turf, where they could reward their loyal men with a nice job:
- the situation in company is really bad
- maybe the situation is not so bad, but there is mismatch between what voters expect and what they receive. By privatising the business, the gov is no longer to be blamed for its perceived failures.
- people are really unhappy about taxes and selling the business seems like a good idea to get some quick cash before next election. (anyway, when you need to resort to such moves, then presumably you have been defunding it anyway for a while, exactly as Chomsky suggested)
Conclusion: Chomsky is presenting symptoms of a naturally occurring process of selling some problematic or mismanaged government enterprises as some conspiracy theory. He really needs that, otherwise he would have to admit that government owned business in general are not destroyed by some malicious conspirators, but just run ineffectively for years.
