The government needs some influence on some parts. If you privatize everything, the hospitals wouldnt be able to keep up. The police enforcement, the ambulance, the firefighters organisations would be shut down fast. Also, if you privatize everything, so including infrastructure, there would be a big big mess. Believe me.
The crisis in Holland we have now, is saved by the government taking over the Rabobank and ABN AMBRO banks. If they didnt, almost the total population of holland wouldnt have a bank account. Holland would be like greece these days.
Now, explain to me why it would be better to privatize everything? Only bad thing happen out of that.
