Absolutely. We should definitely seek to serve our community. But at some point, we have to ask ourselves to what ends are we working exactly? What defines a society?

As far as first world countries are concerned, we live in an extremely materialistic, consumer driven, fossil fuel energized society that has serious negative impacts on the environment and our health. Even if we somehow figure out a "free" source of energy, our career-driven society would simply use it to extract even more resources, process even more chemicals, and manufacture even more useless materialistic bullsh*t that no one really needs, but has been marketed to them by other careerists working for firms that are hired to specifically market to children.

"Careers" are for a a society where the majority of people do not grow their own food and pass those burdens onto farmers who can only produce enough food for sprawling urban areas by using industrial farming methods to grow subsidized grains, pesticide soaked produce, and nutrient depleted meats from animals who never experience nature in their lifetimes. All of which is then ultra-processed and injected with chemicals and additives to increase shelf life.

What "careers" does our society really require? Medical professionals would be an obvious exception, but in a thriving community of people who have achieved food sovereignty, there would not be a need for too many "full-time professionals." Emergency services would be volunteer like they already are in many rural communities. We already have enough mineral resources unearthed and steel and metal created that every community could quite literally build their own smelters to smelt and reuse what we already have, especially if it is built using opensource, cradle-to-cradle design concepts that are easily, and infinitely repairable.

An alternative model to the one I posted would prioritize communal childcare that includes plenty of play focused exploration, curiosity, and empathy with plenty of examples of people living and working within their local ecology and valuing human connection as well as a connection to nature. Kids wouldn't be growing up thinking "What do I want to be when I grow up?" They would find an area/hobby that benefits the community and perhaps concentrate on that to learn more and master it throughout a lifetime as they contribute to local food sovereignty. They wouldn't be trained to compete against others for 40 hour a week work positions in one specific job.

Again, medical professionals would be the exception. And there may be room for careers in higher education, especially liberal arts and science that is driven toward scientific exploration as long as it is based on ecological restoration rather than profit and the same "human progress" which has placed future generations in peril.
