So...if he didn’t spend and didn’t save but instead invested every dollar he got back into his company, then if he shuts it down what does he retire on?
That was during the 10 years he got the biz off the grounf. Look at his quarterly taxes - he’s clearly successful now and has plenty to retire on.
He retires by cashing in on the investment he created over the last 20 years. The same thing would have happened if he put the money in a bank, but the bank would have been creating investments with his money istead, and would have returned it to him at a fraction of the gains they made with his money.
