Let's deconstruct your statement:
>> Who was born in Canada in 1951 near one of the best engineering universities in the world,
He was born in Vancouver; Waterloo, ON is more than 4000 kms away, so not really close. Waterloo was also not the globally recognized institution we talk about today. It was a relatively new school.
>> perfectly suited to benefit from economic liberalization
He graduated from UBC in 1973, in the middle of a recession with economic stagnation and high unemployment. With a degree in mathematics he likely had no choice but to go on to grad school.
>> lucky enough to be interested in computers at a time when almost nobody was and as a result was able to be around the best computer science people.
I'm not sure how you're "lucky" to be interested in a subject deep enough to pursue a graduate degree, but regardless, in the 70's computer science was still not held in the same regard as mathematics and other pure sciences in most of academia. He was obviously driven by a deep desire to explore an emerging field despite this.
No one is saying he earned $10B through hard work, but discounting the luck he helped generate is really petty and unfair.
