If we want to continue the workers existance of being under the thumb of capitalism then fair enough, forget change.
But if we want each and every human to be really free to fulfil their creative self from cradle to grave then change has to happen, with capitalism consigned to the dustbin of history. At present a child is born into its circumstances, as directed by the capitalist forces that have created an elistist system. A child in a poor household, although there will be lucky exceptions, will often not have the environment to study in, will not have the resourse available to advance their education to optinum levels, and certianly will not receive the best standard of teaching as available to the wealthy.
They will leave school never reaching their full potential at that stage, and be inserted into the system that forces you to work for minimal wages in the interests of the ruling elite. If they fall ill due to the pressures of work, there is the NHS to put them right, only for the purposes of them to return to the work that put themselves there in the first place.
That person goes through life having to accept what is; whatever the capitalist market dictates of them. Whatever taxes they are asked to pay, they have to pay it. Whatever it costs to live they have to pay it, or starve. The system insists they carry on working for it, not what they could achieve if freed from the chains that limit their freedom, and knowledge, alienating them from their creative selves.
Plato in The Republic(380 BC), and more recently Kant in his An Answer to the Question: What is Enlightenment (1784) envisage a system where every man has the freedom to be free to obtain the best education and knowledge, away from the 'darkness' of ignorance, to achieve their best potential. Currently the capitalist system allows only for certain 'classes' of people to gain just enough knowledge to meet the demands of the production line, office or other work place to keep the capitalist machine working. This produces the profit that is then unequally distributed, favouring the elite, but not fairly rewarding those who have actually formed the means of production, and by the sweat of their brow created the very product that has produced the profit.
The ideal system is one were those who produce the profit can earn unlimited wages and own property legally obtained. The "supervisors" of the system, security services, civil services, and general support services are their to protect the workers and are paid for by them. The leaders or 'king philospers' provide the ideas, education, and moral leadership for the system, but are not allowed to earn money or own property, but are supported by the workers, in return for their services to this system.
To achieve this would require a revolution, and a whole shift in human thought, as yes it must be recognised as Hobbes (1588 - 1679) wrote man is born naturally greedy and if allowed to will commit war continually agains't fellow man. His ideas of a supreme leader as suggested in Leviathan(1651) could work in the previously described system, but with this 'leader' not enjoying any personal wealth, but the 'workers' enjoying great reward for the labours.
Yes this may seem like a Utopia, which can never be achieved, and probably will not in our life time, or that of our children, and their children. However, one day change away from the capitalist system will be required to create a far better standard of life for every man, woman, and child, than what will be then a discredited system. No more will a few be allowed to gain benefit at the expense of others (look around us now and ask are we happy with what we see??) All will be free as Locke (1632 - 1704) envisaged with full justice as Rawls (1921 - 2002) outlined in his A Theory of Justice (2008).
With a combination of these ideals, and especially considering those of Karl Marx (1818 - 1883) plus many more I cannot envisage now in 2008, we could build a far better world for us all away from the culture of greed and inequality, but have we got the moral courage and physical strength to see such change through? Possibly it will take an accumulation of political developments for all this to transpire, such as with the French Revolution of 1789.
