It probably depends on what government is handling it, all those seem to work well here. Of course there is a drive by right wing parties to save money by privatization and to get more money for their in group that owns the companies providing... seems like every time something is privatized here things stop working and start costing more.
Aye, government ultimately controls all, with management ranging from direct
(micro) to snoozing (macro). The results are always our leaders' responsibility.
As for cost, there's a tricky hidden thing to consider....
Gov exempts itself from things like taxes, building codes, & other nagging things it
imposes upon the private sector. So a private company might nominally appear
spendier (in price), while actually being more cost effective. The moral of the
story...make fully informed decisions based upon analysis, & then manage well.
