work January, get paid 1000, pay 600 in bills and lay 400 aside for potential emergencies
work February, medical emergency comes up but medical bills now cost 10000 so you can’t afford them with the 400 you set aside and you also can’t work because of the emergency so you take 20000 debth to repay the medical cost and other bills
work March to repay your debth, but you only get 50 while still having a debth of 20000
Meaning, you treated currency as an investment. What did I just say?
