Shareholders' cash dividends

I like to suggest SEC that it should instruct the companies to deposit declared cash dividend to their shareholders within 15 days of the record date. The companies have been keeping and using the cash dividend without paying any interest of the monies that are being used for years. I hope, SEC will act soon to make sure that cash dividends are deposited to share holders' account. It will bring these major benefits: lessen shareholders' hassle, increase the liquidity, and improve the reinvestment condition.
