I was going to keep quiet until war boy decided that capitalism due to the nature of the fact that it makes a profit, will cost more than states who employ twice as many people in order to do a job of any size then sub contract out to the capitalists and get an "expert" in to tell them what to do. Take a look at our marina for a start.
But look at the costs. Capitalists will charge a fixed amount which will be tailored to win the quote while making some profit in order to still be employed and market forces will ensure that the quote is reasonable. States will submit a quote, multiply it by three of four over the course of the work, have ten times as many people doing twelve times less work and as Fritz and Sparty have rightly said, once the job is complete, we will still be paying them out of taxes to be employed in their position and then pay them during retirement, again out of taxes that you and I have to pay (at least most of us).
Read up on capitalism, it will explain that it has been the major force in industrialisation and growth, not just in economic terms, but also in health, education and general wellbeing of whole nations. Our lives would be a sorry state without it, like it or not. Of course there are variants on capitalism which have historically not been as good for the population, but you will find that in all areas of life such as Marxism, Liberalism, and even our current semi fuedal states.
Outsourcing contractors would not be a viable alternative for millions of companies if it actually cost more than their existing set up, but outsourcing is massive for one very important reason. It cost LESS and when you factor in the cost of keeping states employees employed once they have completed a job and are busy sitting in their offices looking out of windows or leaning on their spades watching someone else dig, then it saves an absolute mint. Couple this with the fact that any half decent project manager will ensure that late delivery or poor workmanship will be covered in the contract with costs to the states and there is really no reason to keep half of our states employees in their positions.
Of course, states employees will be quickly on here to try to rubbish that, but you would never expect the turkeys to vote for Christmas would you?
