The answer here is that this meant that the US government was to stay out of the people's businesses and by large their affairs. This means that the transaction and deals between the parties happen without the interference of the government, there are no subsidies, no tariffs and no regulations on trade.

Whereas Locke spoke of life, liberty and estate, the Declaration of Independence speaks in terms of life, liberty, and the <u>pursuit of happiness</u><u>.</u>
In John Locke's way of framing his theory, "life, liberty, and estates" all constitute an individual's personal property. We normally think of "property" just in terms of one's "estate" -- that is land, house, belongings. From Locke's perspective, however, our property is <u>everything</u> that belongs to us as persons, which begins with our personhood itself. Having life and personal liberty -- those are the most important things we possess. Then comes "estate" or our land, house, belongings.
Thomas Jefferson's words in the Declaration of Independence have a similar theme, though worded differently. Pursuing happiness--a meaningful and fulfilling life--cannot happen unless life and liberty are respected and protected first.
Until the agricultural revolution, humans were mainly hunters and gatherers who did not raise plants or animals for food.
