You are wrong obviously, but thats ok, hadnt we all been marxists when we were 18? Your definition sounds so good, too bad it has been proven deadly wrong in practice so many times, that I see it as a fucking wonder that people really still do believe in the possibility of marxism being applied in practice. You say marxist regime - wow - would solve many, many things. Equality and justice? Come on! People are not equal, never have been, never will be, its against the natural course of things. Therefore, you have to tell them to be equal. But how do you do that, cause there are plenty of folks who simply do not want to be told what to do? Well, you force them, easy. You surround the country with barbed wire, you ban all oppostion, imprison or kill all its members later. You rule the economy, everything is cheap, but there is no choice (really, the only car you could buy here was LADA and there were looong waiting lists for them - then, after 2 ot 3 years you got e.g. a green one, so you took it even though you hated the colour, because that was the one you got, period). Socialism doesnt give you an opportunity (yeah, well, it does, join the party and be more equal than others), it tells you what to do. It takes care of you, right, makes a parasite of you, totally incapable of independent action, a lazy bastard (this was the case of applying marxist ideas on gypsies here - they have always been travellers, nomads, who came to a town, repaired some pots, played at the weddings and funerals, earned some money and left, thats why people liked them. But they were always living in improvised sheds, were dirty, so the commies said no, we will give you flats and social support and will take a good care of you. So now there is a large Roma ghetto in every town and village, gypsies dont do anything but multiply and destroy the place where they live and everyone hates them). Not to speak of the fact that socialist economy creates a huge debt and sooner or later goes bankrupt, which sometimes leads to famine, sometimes to civil war, sometimes only to a huge crisis.
Capitalism has its undisputable vices, but these are I think outweighed by its virtues. Extremes are bad, whether on the right or the left. But I think capitalism is a lot people friendlier and above all, has been proven positive in practice a lot more than communism. You said, your parents unfortunately left Britain. Why that if you like marxism so much? The fact that you actually can criticise capitalism proves that its way better than socialism, where critical thinking is seen as an attempt to violate the principle of equality and equally punished.
I dont say that people and free market should take care of everything. But I dont think socialism with its totally centralised way of dealing with things does better. Free market governments try to lessen their power and tranfer it to the regional authorities. And thats the key I think - state will never become a community, but a municipality can. Regional governments can and should do the redistribution of wealth the state fails to do, regions know the situation best and should build homes for the disabled, orphans etc. The redistribution has got to be addressed and people will gladly contribute, because theyd know what its for. But overall? You have HUGE taxes in every socialist country and very very very untransparent distribution.
