The economy exists to serve the people not the other way around. The purpose of life is to preserve and develop life. If the economy is making it hard to live and reproduce the economy is maladaptive and will fail.
The problem is that the people refers to a group as a collective. The economy deals with individuals that make up a group. Individuals always triumph in the long run, which means that if you set rules where you discriminate against individuals that want to be different for the benefit of the group then you end up with a system that will eventually collapse.
Reminds me of a time when G.K. Chesterton saw a banner that asked, "Should store clerks be allowed to marry?" To which he retorted, "Should store clerks be allowed to be store clerks?" We do tend to forget the proper order of things at times.
