I would put X% in Vanguard 500 Index Fund[1], and in Y% Vanguard Total International Bond Index Fund[2].
X% should represent the amount of money you can afford not to touch during the entire economic downturn.
Y% should represent the amount of money you want to be able to cash out at any point during the economic downturn.
Another alternative to S&P-500 for putting X% in is Nasdaq-100[3]. It has performed much better over the years, but it's significantly more tech-focused:
> The table below and the charts above display historical performance figures for both the Nasdaq-100 TR and the S&P 500 TR between Dec. 31, 2007 and June 30, 2020. Despite recent overall market volatility, the Nasdaq-100 TR Index has maintained cumulative total returns of approximately 2.5 times that of the S&P 500 TR Index.

(20xx is the year you should be retired)
> Mean reversion in finance suggests that asset prices and historical returns eventually revert to their long-term mean or average levels
The avg. 7% per year will break down into very good years and bad years. Let's say the S&P500 is already down -5% YTD and has underperformed over recent years, then you would it considered to be low, because you would rather expect the performance to increase in order to match the long-term avg. of 7%. So at this point you would happily buy in and expect mean reversion. But of course there's no such thing as perfect timing (except in hindsight) and no guarantee for mean reversion to happen.
The 4% rule of thumb was calculated to minimize risk of running out of money during the time period. 1.5% * 30 years = 45%, so an investment that simply keeps up with inflation would leave you with more than half your cash after 30 years.
And note that the stock market almost always has positive real returns over periods as long as 30 years (see William Bernstein’s book Deep Risk), so the assumption “just keeps up with inflation” is already very pessimistic.
For most people, being able to retire and never work again with 95% certainty enough, especially when tweaking consumption and tweaking side income are easy knobs to turn. No reason to delay retirement 20 years to be 100% confident. Raises the risk a lot you just die before you retire.
What is your basis for believing that the safe withdrawal rate will be less than half this, at less than 1.5%? That sounds excessively pessimistic to me.
That's very simplistic one-sided view of interest rates. If interest rates stay low or go lower, the stock prices will keep skyrocketing which balances the equation on the other side increasing your stock portfolio returns. The P/E capacity will be much higher than it is today in a perpetual low-interest-rate environment.
But there are other good dividend funds and/or individual equities.
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.
