I'm not a huge T r u m p fan but, it is hard to argue against his actual policies versus the Rhetoric and harsh media bias against him.
The Crimea invasion happened under O b a m a, Syria crossed O b a m a 's "redline" with no repercussions, and B i d e n 's pullout of Afghanistan was an unmitigated disaster for the Afghans, our NATO partners, and our own Servicemen and Servicewomen. Many people argue this is what emboldened P u t i n to invade Ukraine.
The effects on our individual paychecks, taxes, inflation, etc. under T r u m p versus B i d e n are easy to see for each of us. How many of us are taking vacations or replacing worn-out cars?
In terms of retirement, ignoring the devaluation due to inflation, most people have much smaller 401K's today than they did under the prior administration.
If you aren't earning the rate of inflation in your 401K, you will have less spending power in retirement than you do today.
Most people have retreated to safety in their 401K's so, the value of their retirement income has fallen significantly.
For those seriously interested in things like this, I would suggest looking to Greece, Italy, and Spain to see the results of the trajectory we are currently on with Trillions being thrown at failed political boondoggles.
