Pushing on a string is a figure of speech for influence that is more effective in moving things in one direction than another – you can pull, but not push.
If something is connected to you by a string, you can move it toward you by pulling on the string, but you can't move it away from you by pushing on the string. It is often used in the context of economic policy, specifically the view that "Monetary policy asymmetric; it being easier to stop an expansion than to end a severe contraction."

“Amongst the learned the lawyers claim first place, the most self-satisfied class of people, as they roll their rock of Sisyphus and string together six hundred laws in the same breath, no matter whether relevant or not, piling up opinion on opinion and gloss on gloss to make their profession seem the most difficult of all. Anything which causes trouble has special merit in their eyes.”
