I think I know what you mean... You maybe mean some people who have this problem might be good or a lot better off if they made some no spending days maybe, if anything, just to get them thinking more about their own spending maybe, or what's essential and non-essential to them, or a the difference between a necessary need and a want maybe, etc...
And I think I agree that something like that might help them maybe, or be a step in the right direction maybe, etc...
God Bless!
