Humans cooperate in the production, distribution and consumption of goods and services. Hunters, both human and non-human, often hunt in groups to increase their chance of success. Tasks like gardening, cooking, and making clothing are often family if not community events. In today's society, the production of even apparently simple tasks like preparing a meal require the coordination of thousands of people.
How economic systems have changed
The first economies involved taking natural resources (e.g., plants and animals) from the environment and sharing with family. Gradually humans expanded both their network and the items they shared. Tools (e.g., axes, cooking vessels) were traded with other families. But even then, the family was often the economic unit.
Your grandparents might have worked on a family farm or in a family business. It is still this way in much of the non-developed world. You, on the other hand, are more likely to work for a large corporation, or service organization (e.g., school, government, social service). As societies industrialize, economic activities move outside the family. Since parents have less control of their children's access to goods and services, the family adapts to these changes. It is now common for individuals to select their mates rather than parents choosing their children's mates. Nor are individuals limited to work working in family businesses or having the same occupation as their parents.
Our US economic system is based on corporate capitalism. Work moved from the home to the factories and offices. In fact, our society is considered post industrial because most people (about 70%) work is in the service sector. I am in the Education business. Not only is it part of the service sector but education employs more people than any other sector of society.
