It seems tat for too long a good /bad economy was associated with the POTUS......of acknowledging them when he makes them. like a responsible adult.
You are completely wrong. It works this way. When "your guy" is the president, everything good that happens is his doing and everything bad is the fault of the last president from another party.
On the flip side, if "not your guy" is in the Whitehouse then everything good that happens is because of the previous president from the other party and everything bad can be laid at the feet of that president. It's call the cannuck law of politics (named after the brilliant political commentator who came up with the law)
The law applies to Canada as well but also includes a sub-section explaining the effects of having provincial and federal leaders of different party's at the same time. Take Saskatistan with Brad Wall as Premier and Justin Trudeau as Prime Minister. Without cannucks law to clearly explain who is to blame for failures and who to applaud for successes, people like Petros run the risk of Sudden Cranial Paroxysm.
