Ramsey is a mixed bag and best utilized in conjunction with other investing gurus(Bogle, Buffett, etc)
Like yourself, I disagree with him on the whole credit issue.
Another big subject of contention is fanatically paying off the low interest rate mortgage.
Peace Of Mind Versus Math, in my opinion.
The S&P 500 or a broader fund such as the Vanguard Total Stock Market Index will double those returns even under the most conservative of estimates.
But Dave has THE BIGGEST FACTOR on his side. Motivating people to DO SOMETHING. Putting money in the account.

And that's why Dave Ramsey should stay away from investing advice and stick to debt elimination advice and personal savings advice, just like Bogle sticks to investing advice and Buffett sticks to basketball advice.
In that video, Dave Ramsey sounds to me like he's making excuses for giving bad investing advice..."at least I get people to invest."
The investing advice from Bogle, Buffett, Bernstein, etc. to invest in low cost index funds is not about superior returns. It's about low fees and diversification. In other words, more money for the investor to reinvest and less unnecessary risk.
Dave Ramsey's investing advice is unnecessarily and dangerously risky and expensive. And Dave Ramsey might be getting paid off by the fund managers he pushes. Even if he's getting people to invest, those people are losing hundreds of thousands of dollars to unnecessary high fees and unnecessary risk, and they are probably indirectly filling Dave Ramsey's pockets.
Again, the guy has solid debt elimination and personal savings advice, but he should stick to that.
BTW, Dave Ramsey calling people he doesn't know moron and stupid on the Internet, and he doesn't look like he even lifts. If I didn't know better, I'd say he's an average Getbigger.
