We’re living in the ‘G-shaped economy’—where boomers control $90 trillion, and everyone else waits

The G-shaped economy is a trend where baby boomers control $90 trillion in wealth, while younger generations struggle financially. Wall Street expert Ed Yardeni coined this term, pointing out that baby boomers dominate consumer spending, which accounts for about 70% of U.S. GDP. With a net worth of nearly $90 trillion, boomers are the wealthiest generation, holding 54% of household stocks and mutual funds, worth close to $30 trillion, and owning 41% of all household real estate.

The concentration of wealth among older generations, particularly baby boomers, suggests that consumer spending is increasingly driven by accumulated retirement wealth instead of labor income. Boomers own around $3.1 trillion in money market funds, providing them with more interest income as rates rise. They also have a significant share of mortgage rates, which they are reluctant to give up, leading to higher home prices.

The high share of cost-burdened older homeowners and substantial non-mortgage debt indicate that many baby boomers have limited financial flexibility and potentially less wealth to pass on than previously thought. Despite being the wealthiest generation, boomers still carry significant debt, including mortgages, credit card balances, and personal and business loans.

Although the AI boom is a major driver of economic growth, younger generations are still struggling to secure jobs and accumulate wealth, as they are more affected by rising interest rates and limited access to housing markets.
