It is good to have a credit card balance if building one allows you to make more money than not having one at all.
An example of this would be to spend $800 on parts to build a trailer that you sell for $4000.
Without a credit card balance, you wouldn’t have made $3,200.
The problem is that for the most part people build credit card balances spending on themselves.
For a credit card balance to be good, you must spend on others.
Who are you spending on?
