I'm not gonna pretend I know about the specifics of DB, but tales of crappy public services are plenty around the world and a lot of the critique is aimed at enabling privatization.

My anecdotal evidence is that these public entities usually suffer from lack of funding or incompetence fueled by corruption, that usually takes a few forms: - the contracting of work to a third party with kickback (incentives to continously do sloppy work) - inaction due to lack of corrupting opportunities (leaders try but cant set up a good fraud scheme) - nepotism that leads to incompetence

And lack of funding can and has been weaponized to cause a shitty service to then set the pretext for privatization. Usually there are private interests behind this public policy decision.

The more menial reason for lack of funding is sometimes massive spending or subsidies for capitalists elsewhere which skews the budget.

And of course also the intense bureacracy needed due to lack of democratic control. Yes, im saying people dont actually have a say and they could have a say. IE delegate democracy.

These are just universal problems of modern capitalist economies and their bourgeois politics.

Quite possibly DB suffers from these more intensely than others.
