Had a 'poor' friend I'd hang with at the University Library. He somehow would get fast food or restaurant food, he worked at a car wash and his uncles cleaning company. Met him in 2014, and in 2017 he had a panic when he was kicked out of his house. He came over for a moment and asked for any spare change, gave him ~5-10$. I was eating raw ramen and protein shakes, always cooked at home. Saved like crazy(and worked). No college debt. Graduated, life is good. 5$/day is enough to pay for many months of rent. >pretending that saving $5 could make any kind of difference. This is the difference between the wealthy and poor. The poor can't visualize that 5$/day-> thousands of dollars.
