There were no soviet states in 1900, yet I said that socialism was a serious force back then.
Those things are not what I understand as socialism. Socialism to me means to fundamentally alter the economic system, it means an alternative to free-market capitalism as we know it. Not - as you apparently understand it - welfare schemes, public services and a bit of regulation and... some unions. Perhaps such things share fundamental values with socialism, values which are opposed to the values associated with free-market capitalism. Perhaps that makes them socialism-themed or something. But socialism itself already has a meaning. Should that original meaning be no longer necessary (other then so understand the past where it still was in use) it would only substantiate the notion that socialism was dead.
edit: Interestingly, if we look at how the meaning of socialism shifted so radically we arrive at the same basic reasoning Snorrious embraces.
In the USA certain measures have been branded as socialism out of the vague fear that such measures will lead the way to some kind of authoritarian socialist hell hole. The idea is that if you do certain things which are 'socialism-themed', which are opposed to the values of free-market capitalism, you will have to end up in said hell hole on the long run.
Snorrious argues pretty much the same thing, just with a focus on legal and social equality.
just questioning your basic assumtion about the values of free-market capitalism
what are the values of free market capitalism, surely they would involve no regulation and the free movement of people as the market decides, so open borders,
socialists actually don't think that capitalism has values, so it would be hard to be opposed to them, it is just a mechanism, if it had values it would embrace the free movement of cheap labour coming in from across the borders... it would be very multicultural
the problem is that too many people define socialism and the left as things that are opposed to free market capitalism, but they still have laws that affect people, fair enough, but they should be liable too the same laws, that is a leftist view,so equall rights are prominent
they then tag on things like property rights and say the left oppose them , no the left thinks every one should have the right to a roof over their heads...
as capitalism has no values, and both left and right already make laws and regulations to manage it so it can benefit people, the only debate is should it benefit the lowest paid people as well, so they can have families (with the much alluded to values of) or should it mainly benefit a group who already have benefited from it, and wish to maintain their lead in this...
