All societies have both social, ie: publicly owned/run features, and private enterprises.
I'd advocate public ownership and management of The Commons -- those necessary services used by the entire population. This would enable complete transparency, in expenses and management, at wholesale cost.
Discretionary goods and services could be left to free enterprise by profit driven entrepreneurs.
Services like the electrical grid, water, sewerage and waste disposal, education, police and emergency services, the courts, food/water/air quality inspection, insurance, healthcare, and roads could be co-operatively managed.
Car repair, landscaping, plumbing, bicycle sales, pubs, office supplies &c, could be left to private enterprise. That's modern socialism.
