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.
To support your motion I want to bring some examples, take a look at countries that have thriving private sector, the difference between the economy of the country is different from those depending on their government to do everything for them like in most third world countries. The government can't provide all the jobs, they can either make policies that'll favour the private sectors and make them very attractive to foreign investors to come in but for them to solve all the unemployment crisis is impossible. I don't think there's any country that don't have unemployment problems but the difference is the percentage of people that are unemployed and those employed that determine which country is doing better.
The high rate of birth is also a problem because many human beings are being introduced without enough jobs available because still have those turning adults and they need to work. Roberts and AI are taking over jobs and people aren't advancing to meet up with the demand of the new jobs but still caught up with the assumptions that they'll go to college and come out to a job waiting for them.
