Professional athletes and entertainers earn a huge amount of money that is hard to imagine
It is true that professional athletes and entertainers earn a huge amount of money.
Most of the people spending their whole life can never achieve this.
while other professionals earn significantly lower.
-do those professional athletes and entertainers deserve this money?
whether they deserve this huge sum of money
From my prospect,
In my opinion
Therefore, those who are paid high salaries must exceed others and achieve something incredible in certain ways
Therefore, those who deliver exceptional performance are likely to earn higher salaries than others.
show ourselves
prove ourselves
how may difficulties they've gone through
how many difficulties they have overcome
how much cost
how much/the cost
Fairness is not about equal payments for everyone, but equal chances to acquire the same goal or accomplishment.
I think this is a strong point :)
I hope these help!
