Belief in God is rational.
Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED. (You could prove the first step a priori that everything has a cause by noting that nothing can come from nothing. This makes it a priori, not just an empirical observation).
Salaries are a price, just as the price of chocolate is a price. Fast Food Workers: You Don’t Deserve $15 an Hour to Flip Burgers, and That’s OK
Salaries are a price, just as the price of chocolate is a price. They’re just the price at which someone’s work sells. This is true no matter what your job is or how much you’re being paid--if your wage is the price at which your labor sells, the salary a CEO gets paid is also the price at which his labor sells. So we shouldn't give a different explanation for the wages/salaries of rich people from the explanation we give for the wages/salaries of poor people. All salaries are determined by supply and demand for the labor in question.
