Luck was not mentioned to diminish what the person has accomplished. It was intended to point out that their story may be difficult to replicate.
"I made it and you can too."
Note that I emphasized "can" in that quote. "Can", not "will". This isn't a guarantee by throwaway-0987, it's words of encouragement to try.
On a forum that celebrates startup moonshots, I find it odd that anyone would piss on the idea that trying is worth while.
The thing is, socioeconomic status affects our outlook. It doesn't matter if you're poor, rich, or somewhere inbetween. A simple example is taking advantage of opportunities. You may be unaware that they exist, view them as being out of reach, or simply see the risk as being too high. Only one of those even imply that chance plays a role. It is also worth noting that values may play a role. Some people like to blame being poor on bad decisions. While it may be true that some decisions are bad in the sense of generating wealth, they may be good decisions in other respects. Many jobs serve have social value or serve the public good, yet are woefully under compensated. Some people will choose that path simply because they are more intersted in serving others and simply don't have the will to be selfseving.
I think the "can" is applicable here and can think that even while acknowledging there are people who can't physically work. I don't want to put words in your mouth, so I'll ask: is this the only reason you object to using the word "can"? What would be more accurate in your view?
