So what. Does he have some kind of moral obligation to be? You're a fan - it's his job and he's no more required to be "passionate" about it than you are about yours. Frankly, if I were him I'd not be feeling to chuffed with life at Madrid given how he's been treat.
Real were happy to pay him mega money when he was winning CL titles. Now they're bored with him and want to quietly push him out the door just because it suits them to bring in some other galactico. The ways he's been treat is disgraceful. Good for him I say.
I don't think anybody feels it's any kind of 'moral obligation' to be passionate about their job - however, some of us enjoy what we do and want to give off that positive energy in our work. I agree about Real Madrid's capriciousness and ruthlessness - it's one of the reasons I don't like this club and never have.
Gareth has choices unlike many people because of that money and would with much less than that - yes Real are not treating him well but he is choosing to stay. Decisions and consequences. Some other players in the same position would move to another club to enjoy their football and be appreciated again and be in the position of challenging for trophies.
Just because you won't be earning the equivalent of GDP of some countries doesn't mean you can't leave Real behind and have a great career again. Ooh, he's being victimized - no, he's choosing to suck it up. His choice.
You're over-simplifying the issue. Gareth Bale is not some wronged innocent - like Beckham and every other non Spanish footballing big name that joined Real, he knew what this club does. They've done it for decades. Buy success, are ruthless in dumping and buying players.
Gareth signed on for the bloated Real Madrid salary - lucky him but guess what, all that money comes with the not even fine print that you signed for a ruthless club like Real Madrid. He did this in full knowledge of what kind of club this is. He wanted to be a 'Galactico', he turned down other clubs and the choice was his.
And no, I can't feel sorry for somebody earning that money especially in the context of how most people on this planet struggle, many die everyday because of lack of money and resources. Over-paid sportsmen sign the devil's bargain - take the frankly obscene money, take everything else that comes with it.
If the player wants to stick it out instead of going somewhere they'll be appreciated but won't be earning more than the GDP of some countries - that is their decision that doesn't require sympathy.
