No, I didn't drop a link farm because I figured most people would already knew this. I mean, it doesn't even pass the common sense test: if hard work = success why aren't most, say, Mexican immigrants loaded?

I suppose it depends on what you mean by success. But by the most common definitions (e.g. being rich) hard work isn't the main factor or even required at all (e.g. inherit millions from your parents requires how much effort? Basically not dying).

I watched my dad hold down two jobs and come home and work into the night providing his family with the things we needed. The first career job I had made more than he's ever made in his life and that job was mostly standing around.

Sadly, how we really wish things were has nothing to do with how they actually are.

For instance, academic success is about 60% socio-economical background, 15% professors, which lets only 25% to individual variation. Similar data can be found in many domains, like the importance of geography on a country economic success, etc.
