If you're trying to pragmatically build a more equal and just society OTOH, you will inevitably end up using prices and market economy in *some* areas simply because they work better than command economy.
While it *does* make a lot of sense to regulate prices of medicines and many other things, it does not make any sense to meticulously plan production and regulate prices of socks or toilet paper.
These things are better left to the market. But this is "capitalism", isn't?
