Since the general public no longer has any regard for the Lord's Day we are subject to subtle slavery and oppression. No business is prepared to lose money or custom by staying shut. The few that wanted to trade forced others to keep up with them. If you ask the proprietors of most businesses they will tell you that they regret the loss of the Sunday off. Effectively they have become slaves since most will also admit that it is not even very profitable to stay open for so much time.
People only have so much money to spend anyway.
Man needs regular rest if he is to work well. We can't enjoy fulfilling our dominion mandate, of which work is a major part and thus glorify God, if we are not regularly refreshed. Inevitably people will suffer more and more from stress which will have its destructive effect in the community. Witness the rise of such ugly behaviour as 'road rage'. As Christians we may find it becoming more difficult to participate in recreational, cultural and community activities.
