With respect, I think you are confusing the way dividends are calculated/paid, and this limit I raised.
If I owned 10 shares, and the company declared a dividend of X% per share, I would get that, times 10. And I would continue to receive it until the company stopped paying a dividend, or I sold my shares.
Under this idea, if those 10 shares had been given to me from other shareholders, (for free), I would be paid the same dividend, until I had received the limit of say £500. The company would still pay a dividend to shareholders, but not me now. That would now go to HMG.
I have seen far more detailed analysis than the FT up there about this, and the money diverted to HMG is billions and billions.
We're all equal comrade, just some are more equal than others.
