But the fewer people you have working, or not making enough money to support themselves, the smaller the economy will be and the less revenue that you'll have for people who aren't physically and mentally able to at least work full-time and able to support themselves. Which is why you need the largest workforce possible with the largest middle class possible. So you have the fewest people possible who are either unemployed, or undereducated and not able to get themselves a good job that will allow for them to be self-sufficient. And then you'll have more money to help people who truly need it.
Private enterprise and capitalism are great things and I'm big fans of them. But they can only be as successful as their workforce will allow for them to be and be as good as their workforce. You need a good infrastructure system, good education, good workers and a good and efficient regulatory state, for your economy to be as strong as possible. To have the largest middle class possible. As many people as possible who are doing very well and even able to put money away and enjoy the luxuries in life. And for the people who fall through the cracks of system, an insurance system to help them out. But have that population be as small as possible.
