The means of production are not entirely owned by a seperate class nor is the barrier to entry for many industries so high that it is entirely impossible for the average joe to enter.

Sure some industries are nigh impossible to get into, like pharmaceuticals for example, there are much bigger industries that have lower barriers like machine shops (which are really medium entry but you can scale them), and manufacturing via 3d print hubs.

Not to mention aoftware development which is a fucking wonder when it comes to potential money vs barrier to entry.

Certain construction contractors and engineering consulting firms can be opened up with fairly low barrier to entry.

I'm sleepy so my replies may not seem very coherent so tell me if you don't understand what im saying
