An investor must feel certain that he will be allowed to fix any price for the goods and services sold by the public sector firm that he is buying. This is the way to profitability and financial health. The opening of the marketplace to competition, both domestic and foreign. To cancel all laws, regulations, rules, precedents which inhibit or prohibit competition. Subject to the right regulations concerning safety and financial wherewithal - everyone should be allowed to do anything.
Economic history shows that competition provides better goods and services at much lower costs.
It also shows that the public sector is a potential hub of inefficiency and sometimes blatant corruption. The Public sector is fat and sluggish. It has no right to continue to exist. But certain functions can scarcely be transferred to the private sector. They are usually performed by municipal, local and regional authorities.
