Socrates was a stonemason --- effectively a skilled labourer or tradesman, but not wealthy. He was a footsoldier. In a culture where most were slaves, he was a citizen, but not a member of the aristocracy (notably contrasting with Plato). His long-suffering wife Xanthippe complained of his failure to provide for the family, and Socrates lived simply.

Socrates as a citizen was likely the third of Athens' four classes: slaves, metics, citizens, nobles. Not destitute, but neither wealthy.
