Unless you are born into a rich family, there's no such thing as easy money other than by cheating, fraud, or through some unfair (therefore unjust) social/political/economic/business system or structure.
Or, in very rare cases, by luck, eg, striking big in lottery.
Honest money has to be earned with efforts.
Federal Reserve lending money to banks at near zero interest and banks then turning around and lending out funds at much higher interest is easy money for banks. Worse still, banks use this free money to buy risk free government issued treasury bonds/notes/bills for much higher return. This is, if not sin, crime. Knowingly doing so, the Fed is just as guilty as the banks which are blood suckers anyway.
