Of course you're wrong here, and it's not hard to figure out why.
Your success in life is always determined by other people, they evaluate you constantly and then find an adequate place for you on the dominance / competence hierarchy.
And to determine your value, anything that brings value to the world will be taken into account, that's your intelligence, your potential, your personality make-up, your skills, but most importantly your looks. It's not that hard to figure out, just look at how much value good-looking people are able to generate, how much male models get paid, how much more likely they will be cast in movies, how much people admire them, sometimes just because they look good and very few other reasons.
It's not about being a victim, it's about assessing how reality works and not being bitter and resentful about it, which is why you'd like to believe it's false. Yes, humans value looks a lot.
No you cannot do anything you want in life, that's a blatant lie. I don't see why this needs any further explanations but I guess nothing is truly obvious in life: you will never become a male model if you're average-looking, you will never succeed in the NBA if you're 5'5, you will never succeed in university if you have an IQ of 95, and you will never become a ruthless successful salesman if you're highly introverted and agreeable. Looks, height, IQ and personality are all almost entirely genetic and there's little to nothing (for height and IQ) you can do about them.
Success is not a decision, success is hard and rare and it depends on a many factors and a lot of them will not be under your control. Even the propensity to work hard (conscientiousness) is largely genetic.
Stephen Hawking is a one in a million kind of guy, brilliant and highly creative. And truly creative people are extremely rare, your average guy out there won't have the IQ, the creativity and the other attributes that contributed to his success. Not everyone can become anything he wants, this naive optimism that's quite pervasive in our culture has to stop.
By the way, about Stephen King (edit: OK I mixed up Stephen King and Stephen Hawking, this is still relevant though), did you know that he gave up on writing at a point? He threw the manuscript of Carrie into the garbage bin because of the harsh rejections he got from many publishers. It's his wife who picked it up from the garbage bin and convinced him to persevere. But "winner attitude!", yeah right, he can thank his wife.
Oh and your last paragraph, more of the same unsubstantiated nonsense, one more obvious truth: not everyone has what it takes to become an entrepreneur, much less a successful one. Entrepreneurs are highly open, creative and extroverted people and again, those traits are genetic, and let's not forget that you need a high IQ, which would also be necessary to get a degree in economics, you'd need to have an IQ of minimum 115 (that's 15% of the population by the way) and to also be highly conscientious (which narrows the sample even more).
My conclusion: you have no idea of what you're talking about here, and I suggest that you educate yourself about the realities of life because if you keep up with your mindset, life will end up devouring you alive. The level of naivety and of willful blindness that you exhibit is dangerous to say the least. I'm not trying to be mean but to help you, and I don't pretend to know everything by the way, if you have any reasonable objection to anything I've said, don't hesitate to tell me.
