Yes, the Walton family is EXTREMELY wealthy and don't work in the business. They are wealthy because of what Sam did YEARS ago. The work and investment and sacrifice that Sam put in for many years of his life. He passed the benefits on to his kids. Today, the Walton family lives off the dividends. They get the same dividends as the woman you mentioned. Last year was 3.25%. The same amount that any current employee can be getting.
At current stock prices, $79, an employee could have $20 a week taken out of their check. That would be 1 share every month. After 1 year, that would be 12 shares. If a kid started at 18 and worked 42 years, that could be 504 shares. Just at current prices, that would be $39,816. That's without compounding. That's without increasing investment. That's without stock splits or changes in price.
3.25% dividends is better than any bank pays and better than inflation (for now).
Then the person could take that 39k and by most of an SUV. Not much of a retirement plan :)
