I think they just take 25% of income going to savings for granted. Everyone has a 401k, an IRA, an emergency fund, and if they're really doing well, an investment account. "Savings* to these people are their fun money. It's what they dip into because the new phone just dropped and they want it now, not later. Or it's what they plan to spend on large purchases, and don't even begin to think about having to compromise their lifestyle to afford a new fridge or washing machine or bi-annual vacation. They have no concept of people whom have exclusively a couple thousand or tens of thousand--and some amount of equity in their home if they're lucky-- and nothing else to their name. For the bottom 3 quintiles of wealth in this country, any rise in the stock market is literally immaterial to their well-being.

"When It Comes to the Value of Their Holdings, the Wealthy Far Outpace the Rest-- When measuring the value of stock holdings, wealthier Americans have more money invested in the market. Families in the top 10% of incomes held 70% of the value of all stocks in 2019, with a median portfolio of $432,000. The bottom 60% of earners held only 7% of stocks by value. The median middle-class household owned $15,000 worth of stock." -US News article
