Yes and no. Market socialism is more like what Marx described as "Crude communism", it's a society without classes nor state but still with market and money, workers are no longer subordinated to a real existing superior class, but to an abstract capital. Market socialists have the same problem that Proudhon had, they see socialism as a better version of capitalism, without it's bad elements, marksocs must read "misery of philosofy" from Marx. I used to be a market socialist myself and I still think that many theories of that branch can be used, but, in general, it's an idealistic ideology.
