I would say this is pretty normal. Everyone thinks about life and salary and a linear path to wealth, but its not true.
Not everyone stick in a company for 10 years. Some take sabbaticals, some have medical bills, some go travel for 2 years.
I was earning peanuts up until my early 30s. Also if you are not in US and not in Tech which is lets face it, majority of people - you are nowhere near these numbers.
Survivorship bias at its finest.
Of course is not that simple. I won't bore you with my life history, but I spent most of my career living paycheck to paycheck, and only got a high paying job recently. With the double wammy of moving to the US and stock plummeting, my life savings are paltry. I'm still renting and I project it'll take me 2-3 years to save for a down payment.
In fact I'm confident that if you graduated 3 years ago and have been working in tech in the US, you'll likely have more wealth than me.
