What investment gurus get wrong

Investment gurus' advice reflects and reacts to their countries' financial habits, such as Americans' high debt or Britons' aversion to stocks.

Dave Ramsey, a 65-year-old radio star, advises Americans to pay off mortgages early and avoid debt, responding to high consumer spending and credit-card delinquencies reaching 13% overdue in early 2026.

Martin Lewis, founder of Money Saving Expert in Britain, focuses on penny-pinching and only recently promoted stock investing, mirroring Britons' low equity ownership (13% of household financial assets vs. 44% in America).
