First, 2-5 million net worth is plenty to retire in the middle class and probably leave some wealth for your kids (or donate to a charity, whatever). And it's very achievable by an average white-collar professional. Easier yet if you're half of a couple. For most, it critical to save some early and regularly, but also increase the savings as you move into high-earning later career years.
But the jump from that to tens-of-millions is a literal order of magnitude more money and a figurative order of magnitude harder to achieve. You don't get there from any salary-based savings, even if you save well and get lucky on timing market swings over a 20-30 year career. It just doesn't happen for most professionals, even in management. Hell, I'd guess most C-suite don't get there either.
Even after years of browsing this forum, I'm still baffled by the financial bubble many y'all exist within.
