Russia tried this with communism.
Everybody had a job, industries were owned, run and supported by the government. Hotels and restaurants were all government owned. Nobody had to make a profit.
What happened ?
Nobody had an incentive to do a good job, or improve their business. No incentive to reduce costs, or provide a better service than any other hotel or restaurant.
Often items cost MORE because they were never encouraged to save money or reduce costs.
Think of the UK a few years ago when we had British Rail.
Government owned, and the staff did not give a damn about the customers or providing a good service.
I remember a case years ago on a bank holiday with a reduced train service. I got to the station on time, but the train had gone.
I had to wait an hour for the next train. When I had a moan at the conductor he said that often when there are no passengers the trains arrived and leave early.
I said that was not very good, and he looked down his nose at me as if to say do you think I care.
Not saying trains are perfect now, but at least they have to try to maintain a good service, and meet targets. If they dont they can lose their franchise, so they do have some incentive.
