I think we are over taxed!
Governments should raise enough taxes to cover their costs (schooling, medical, social programs, national defence) with maybe a little extra set aside. Anything more than that is removing $$ from private sector and transfering it into Gov. Gov by it very nature cannot compete with the private sector in terms of efficiency and innovation.So all these large GLCs and huge surpluses are NOT a good thing.
I think if you asked the speakers in your video whether Gov should own businesses, whether Gov should operate businesses to compete with the private sector, they will say NO!
