Not everything in a country can run by a government so which itself enough why we need private sectors to keep things in balance, of course government bend their rules in favour of them for whatever reasons while private sectors create job opportunities that again help someone to make money and they will spend the money they earned so that will obviously help in the development of economy in a country.
Without the help of the private sector I don’t think many countries will survive, the reason why I said that is because of the way some countries' governments operate, some governments are very corrupt which leads to the people of the country not being able to survive, private sector is like another alternative for people to survive without depending on government assistance, there are many countries that the government did not employ many people but with the help of private sector they can be employed and get paid by the private sector to pay for their services without any assistance from government.
We all know that the government has power over the private sector and the private must follow the rules and regulations that the government comes with but some private sectors are even doing better than the government sector, private sector make the people forget about the government and if you look at some countries today you will see that private sector things are doing well more than the government, even the government workers are taking their children to private schools.
