You're not going to make any friends with that opinion but from a cold economic standpoint I'm inclined to agree with you.
It's how it is, I'm not that rich at all but if I lost my job tomorrow and heard that Rooney was having a 2,000,000 birthday bash it wouldn't make a difference to me. He brings that money into Manchester United and he gets paid it back. You are entitled to spend your money that you earn.
You get paid a proportion of what your company earns because of your work, that's how wages work, if you make your company more, you get paid more. If your company makes little money, you get paid little money.
Comparing someone whose company makes say £10,000,000 a year and pays its staff little to someone whose company makes £200,000,000+ a year and pays its staff considerably higher makes no sense at all. It's why we have the stupid outrage in the papers that X person gets a top paid of salary of X amount and that could pay for 567,000 more nurses or teachers. There is no link towards what the rich earn as a direct result of them and their performance/work and what somebody else earns who works in a smaller job who can't afford to pay more.
I doubt many people who earn 20,000 a year would feel guilty about going shopping in Tesco because somebody who earns 5,000 a year can't afford to do it themselves. The attitude would be, 'I work hard for my money and I deserve it and to spend it.' Why should someone who earns more do any different?
I have no right to be angry to Rooney for splashing the cash just because I can't afford to do the same. He has a talent I don't and gets paid well for it. He's entitled to spend his money.
Sometimes you need the cold approach to see the bottom line because that's what matters. Otherwise it becomes silly and blown out of proportions.
