No, your billionaire premise is not correct.
Most people don't realize that share price drops by the exact amount of the dividend on the ex-dividend date when the stock exchanges adjust the closing price.
If you have a $100 stock that is going ex-dividend tomorrow morning for $1, in the morning the adjusted close will be $99. IOW, you will incur a capital loss in the amount of $1 while becoming entitled to receive your $1 dividend on the Pay Date. For that reason, you would not be doubling your JNJ money in one year after receiving four dividends. In fact, an ex-dividend results in zero increase or decrease in the value of your position.
When a stock splits, the number of shares increases and the price decreases, per the nature of a split. If you own 100 shares of a $100 stock and it splits two for one, on the day of the split you will own 200 shares at $50. In both cases, your position value is $10k.
My guess is that Yahoo Finance is reporting split adjusted stock prices (many of them over the years) but it did not adjust the dividend as well, making it appear that JNJ paid a 100% dividend back then. Yahoo is not a rock star when it comes to reliability :->)
