It’s not that complicated. Remove the risk of failure by giving people money for food, a place to live, an education, and protect their health.

There is a reason that many successful founders came from money. That kind acted as a safety net that allowed them to bet big. Not everyone with money goes on to establish a big business but the rate of success is far higher for those with money.

So these measures (public/investments) would be instituted to fulfill these ‘wants’

Most people give what other people can force them to pay to survive.

> if you want other people to give you money you have to offer something they want, not something that interests you

In the small scale.

But if you're thinking about society, you damn well better be thinking about having a big enough place for the people who "need to work with their hands," that's adequately remunerated.

Some assorted observations:

1. Most services are dependent on the use of manufactured goods.

2. Trade exists precisely, because no domestic economy is entirely self-sufficient with respect to the demands of its market. However, when manufacturing is entirely outsourced, you become somewhat of an economic rump state. In the best case, you are now an administrator of manufacturing possessions somewhat like a colonial overseer. This creates a condition of economic imperialism rather than one of economic exchange. It creates incentives to capture the political systems of foreign countries and to depress standards of living in order to maintain low costs.

3. When everything is imported, then the only thing you can exchange for them are services. The alternative is printing fiat money or borrowing.

4. When manufacturing is moved abroad, experience and expertise withers and dies. Entire supply chains and intertwined sectors of industry fade. This creates an economic and even political dependence that goes beyond the mere inability of manufacture. As technology becomes increasingly complex, this creates security exposure. The interdependence of these supply chains is nontrivial.

5. Manufacturing is a basis for technological development. This is the result of not just manufacturing capacity, but the combined and communicated expertise that manufacturing enables and propagates. Once a tradition of expertise dies, it is difficult or impractical to replace.

6. Domestic manufacturing creates redundancy that buffers both the domestic economy and the global economy against single points of failure. It also helps drive prices down.
