This is the different between the rich and the poor. The rich invest in what can fetch them more money (asset) e.g buying land, investing in reputable businesses but the poor out of fashion keep buying liabilities (goods that they keep on spending their little earnings on for maintenance). If 70%- 80% of your income goes to liability then one is preparing for a poor life.
I would say the #1 difference between the rich and poor is.
The rich read books and learn as a lifestyle.
While the poor believe no good can come from either reading and learning.
