You're an idiot.
Saying that doesn't make it so. You're still trying to defend a position you have no defense for.
The bolded part doesn't make any sense. You're investing $5,000 in a company with a potential return of $500. Knowing that the government is going to take 30% of your income in taxes, do you
a) Invest nothing, and get $0 in returns
b) Invest $5,000 and get $350 in returns
And you're here claiming that there is less incentive to make the $350 than there is to make $0? That makes sense to you?
You're neglecting risk.
