You can only take tax reductions so far before the infrastructure that powers productivity starts to crumble.
Taxes have gone way below the level to needed to provide even the most basic maintenance level and this could be held up as the greatest achievement by the forces on the Right. The Right Wing power base, through their institutes, funding and donations, have captured the services of the best and the brightest and the not so bright.
The average person is now at the breaking point and can not afford more "fiscal downloading" or user pay tolls, so it is no surprise to see a Conservative government having to finally throw in the towel and raise taxes. Still directed mostly towards the average person unfortunately.
