Social Class?

In todays society do we have " social class?" Is it still in todays society but more subdued and also not as easy to class?. Me, im working class due to my family work hard for there money and have just a bit of money left over for some fun.
But does it really matter if your Working Class,Middle Class,Upper Class? as long as you arnt stuck up your arse and dont look down on people i presume it really just doesnt matter anymore but in years gone by it did, for instance the mining strikes etc.. so to some up this short and trying to be creative within my writing post I think class is still around but maybe it just isnt important anymore?
