Some things cannot be done cheaply or extremely efficiently but needs to be done.
One of the reason for governments to exist is to deliver services to the communities that, by essence, should not be seen as primarily a source of revenue, but enabling communities to thrive in order to generate an environment where the generation of wealth for the community is facilitated.
And tell me how actually efficient and cost saving having many entities that have as sole mission to generate profit really helped (take a look at privatisation of any entities that were of public interest and the good that it did long term... Spoilers It didn't...)
