This means that the economy must serve the people, not the people the economy. What grows on our land is produced by people and for people. If people are hungry it is not right to produce cash crops merely for profit. If people have no work one should not replace them with machines. But if machines make work easier and more productive for the workforce without making them redundant, then one should use them.
People are more important than things.
People are more important than what they produce. They are worth more than the actual wage they receive. People are more than a figure on a balance sheet. People cannot be equated with their economic usefulness. People are the entire purpose of all our economic activity.
