Billionaires of the 1980s often inherited industrial empires, built wealth in manufacturing, oil, finance, or scaled traditional businesses in a slower, capital-intensive world. By contrast, many of today’s billionaires built fortunes in technology, software, consumer platforms, and new-economy sectors — industries that reward scale, network effects, and rapid global distribution.
Today’s billionaire list is larger and younger in some pockets. Forbes’ 2025 rankings show the global billionaire population rising into the thousands, with most net worth concentrated in tech and finance.
A noticeable share of today’s wealth creators are Gen X (born ~1965–1980) and early millennials (born early 1980s) — people who came of age as personal computing, the internet, and mobile tech exploded. Those technologies enabled faster company creation, global customer reach, venture capital funding, and rapid company scaling. Forbes and several analyses show that a large portion of today’s richest people made fortunes in tech and finance — fields that matured in the 1990s–2010s and attracted entrepreneurs born in the 1970s–80s.
While youthful billionaire success stories exist, most billionaires are still concentrated in the 50–79 age range (many Gen X and Boomers). In short, Gen X and early millennials represent a strong share of new wealth creation today — but the billionaire club still contains many older, established names.
They were old enough to learn new technologies during formative years (early career), but young enough to found startups during the web and mobile booms. That timing gave them both technical literacy and risk appetite.
Cloud infrastructure, global distribution channels, and venture funding let small teams scale quickly. Businesses that once required massive capital (like retail or manufacturing) could be launched and scaled by nimble tech firms.
Many modern founders adopt a deliberate habit of fast learning and iteration. Reading — especially non-fiction, business, and self-development books — shows up repeatedly in interviews with successful entrepreneurs. For example, Bill Gates (often cited) reads ~50 books a year and recommends many nonfiction titles; Warren Buffett attributes much of his edge to decades of voracious reading.
There’s a popular myth that billionaires read 500 books a year (≈41 per month). In reality, documented habits vary:
Bottom line: consistent, focused reading (weekly or monthly cadence) plus applied reflection matters more than an extreme quantity metric. High performers use reading to mix technical lessons, biographies, strategy, and mental models — not just to accumulate titles.
Across interviews and lists, certain non-fiction categories recur:
Selected fiction: While less often highlighted, many leaders recommend fiction for empathy and strategic thinking (recent analysis suggests CEOs benefit from fiction reading too).Business Insider
Biographies & history: To understand decisions, failures, and contexts (Buffett, others).Investopedia
Business strategy & management: Practical tactics and company case studies (e.g., Business Adventures).kevinrooke.com
Mental models & decision-making: Books teaching frameworks (e.g., Charlie Munger’s influence, Thinking, Fast and Slow).
Technology & future studies: For founders, books on AI, engineering, systems. (Titles like Life 3.0 appear on billionaire reading lists.)Most Recommended Books
Self-help / performance & productivity: For mindset, focus, and leadership (e.g., Stoic or habits literature).
Below are titles that repeatedly appear on lists or are publicly recommended by high-profile billionaires. Each is short, actionable, and frequently non-fiction / self-improvement oriented:

Reading fuels idea density. Successful entrepreneurs don’t just read — they synthesize, test, and act. A few practices matter:
Thus, while reading alone doesn’t guarantee a billion-dollar idea, it raises the probability of seeing patterns others miss and having the conceptual tools to act.
Billionaire narratives often highlight luck, context, and timing — and they are true. Yet, across eras the differentiator that repeats is deliberate learning. The 1970s–80s cohort had a technology advantage and the right timing. What unites many successful people — then and now — is the habit of reading, synthesizing, and applying great ideas. In 2025, books remain one of the highest-ROI learning tools for founders and leaders. Read well, test fast, and build.
