What recommendation does adam smith make for a prosperous society that conflicts with the ideas of marx and owen?

government partnership with merchants

maximum freedom for business activities

reform of the worst injustices against workers

education to enable all to fulfill their potential

The best answer for this question would be:

Maximum freedom for business activities.

Because Adam Smith believes in the capitalism of laissez faire. He also developed the natural laws of economics such as the laws of interest which means, that for their own good people have to work. And the laws of supply and demand that we know today.
