There are incremental approaches but they would require states to promote co-operatives and there are simply no political incentives for politicians to do that.

E.g. government grants/loans, subsidies, or allowing workers to preferrentially buy out bankrupt businesses. And that's not even getting into the more radical ideas like mandating worker ownership for businesses beyond a certain size/age/revenue. Compared to the kinds of subsidies and preferential treatment that already exist for certain industries and businesses, these aren't exactly radical, they just lack a powerful lobby and donor class.
