How privatization reduces the monetary cost of public services: reducing the number of workers by 1/3, and paying each of them 1/3 less.

The workers do not magically become more efficient by being paid less. When their numbers are insufficient, they fall behind on the work. The outsourced work is "more efficient" only in the sense that it costs less per worker, and that's due to the reduced pay.

I didn't know, before reading this article, about how outsourcing part of the work in an organization can cause discoordination and rigidity.

To kill dooH niboR, we should restore the workers' old salaries and the rich people's old tax rates.
