The price of the share has to be adjusted at the dividend ex date to reflect the drop of value induced by the dividend payout. If not every holder of the share class benefited from it, then this is obviously unfair.
Now if you are talking about different share classes, then they would have to either be issued to current shareholders (e.g as rights issuance, in which case every shareholder could have them, long term or not), or publicly traded (same thing basically, everyone could have them, long term or not), or privately traded. In that last case, I would not really say this is "for long term investors", it's more a matter of private equity / politics / governance. Don't expect to enter that kind of deal unless you are a _big_ institutional investor.
