Many people ignore these rules. Wages are not the only source of income.
The more different types of income (including investment income) a person has, the more stable his financial position.
We have to open up opportunities for other jobs from free time without disturbing the main work, during the technological era we can get other alternative income from crypto investments or study publishers for adsense income or other jobs according to your talent, so one important thing financial advice is to avoid loans and strive for alternative income to be allocated for future savings.
I agree with you!
I was talking to a girl yesterday and she told me that she has 5 sources of income. Income diversification is very important for financial stability. I also agree with you that borrowing and credit should be avoided. The danger of loans lies in the fact that the borrower must give the lender not only the body of the loan, but also the accrued interest.
Obtaining loans and credits leads to an increase in expenses, not income. There are exceptions to this rule, but they only confirm this rule.
