Edit: if it helps you to invest, by all means, do it. But since dividends are mostly psychological, there is no point in limiting your stock picks to companies with a high dividend.
> a management culture that appropriately balances shareholder interest (by paying dividend)
In theory a company should invest in whatever has the most favorable risk-return profile. If it pays dividends, that means dividends are judged by management to be the best risk-return profile among all other alternatives. A company can pay zero dividends and still protect shareholders interests.
If the reason they "prefer" dividends is not because they evaluated the alternatives and decided that the risk-return profile was favorable (for the company, not for themselves in particular)), then they are acting against the interests of the minority shareholders. That may carry legal consequences or not, depending on your jurisdiction. In my country (Brazil), there are laws protecting the interests of minority shareholders. If you have 51% of a company that is listed on the stock exchange, you have significant but not unlimited power.
Also, maybe the company sees it as a risk that, in reducing the dividend, it may suffer in the short term due to the outflux of shareholders who see it as a dividend play. In that case, the risk-return profile of paying zero dividends is not favorable.
1. I did not say anything about how high the dividend is, only that it has been sustained and has not decreased for a long period of time (multiple decades). Some companies on the list currently pay relatively low dividends as well.
2. It is a heuristic, so it will definitely miss a few great companies and some companies on the list will go on to do poorly (not that any method of stock picking will be any different).

Everything else is the typical movement of any stock, that of course can be detached from reality. The thing is: people are way too focused on the dividend part as if this was the only valid way to investing.
Also note that long-term capital gains are also taxed at the same rate as qualified dividends, but can be deferred into the future. Your argument doesn't seem to advocate for the thing you think it does.
But there are other good dividend funds and/or individual equities.
