Do wealthy people tend to only date and marry other wealthy people?

Red pill 'alpha' guys claim wealthy men don't care about a woman's background and will date poor women, yet they often mock women seeking rich men. In reality, wealthy men tend to date within their social class. Look at Jeff Bezos, David Beckham, or Leonardo DiCaprio—these men date successful women who are already rich or from wealthy families. Even with large age gaps, the younger partners are still well-off. It seems red pill guys overstate the idea that rich men don't care about a woman's status when, in practice, they do.
