I really don’t think you’ve engaged much with Marx if you think the fundamental distinctions between Capitalism and Socialism have changed to the point of calling systems thoroughly dominated by Private Property “more Socialist than Capitalist.” Marx called this Social Democracy “Conservative Socialism,” or “Bourgeois Socialism:”

A second and more practical, but less systematic, form of this Socialism sought to depreciate every revolutionary movement in the eyes of the working class, by showing that no mere political reform, but only a change in the material conditions of existence, in economical relations, could be of any advantage to them. By changes in the material conditions of existence, this form of Socialism, however, by no means understands abolition of the bourgeois relations of production, an abolition that can be effected only by a revolution, but administrative reforms, based on the continued existence of these relations; reforms, therefore, that in no respect affect the relations between capital and labour, but, at the best, lessen the cost, and simplify the administrative work, of bourgeois government.

His analysis is still on the nose for Social Democracy, where worker protections are sliding, and the system itself reliant on exploiting the Global South.
