First of all, you mean petite bourgeoisie, which would be like craftsmen, independent store owners, small businesses, or self-employed contractors.
I am referring to the factory workers owning the factory, or social cooperatives. That might be a far cry from what people wish socialism encompassed, but that is not petite bourgeoisie. You won't find me championing the cause of small business tyrants, lordy.
The Emilia-Romagna region of northern Italy comes to mind, where nearly 1/3rd of the GDP comes from worker or social co-ops.
Sorry you don't like cooperatives, but that doesn't grant you the right to misconstrue my intentions based upon a flimsy, hand-wavy reference to Marxist jargon. We get it, you've read all three volumes of Das Kapital.
