First, there's nothing in the definition of luck that says it gets spread around equally. That would be uniformity, but luck is about randomness, which is (by definition) not uniform.

Second, when you say "sit around watching TV," I presume you're saying that hard work leads to success, and implying that hard work is not luck. I agree with the first part and disagree with the second. What makes someone a hard worker? What makes someone intelligent? Attractive? Likable? Talented? If you keep asking why, and you keep retracing a person's history back to the beginning, then the answer invariable boils down to some lucky combination of genes and environment/experience. Even your ability to improve upon the hand you were dealt in life depends entirely on… the hand you were dealt in life.

All you're doing is making excuses for people sitting around watching TV being just "unlucky". Your life is by and large the sum of your choices.

If you read my post, you'll see that I'm not denying the existence of those choices, but I'm pointing out that those choices are the inevitable result of genetic and environmental factors that nobody ever decided on.
