Is this a bad thesis statement?

My topic: Money in sports The thesis I came up with is: Money invested in most major professional sports is excessive and it would be better to use that money for other purposes. I'm afraid that my topic seems to broad, is it? And if it is could someone please give me an example of a good thesis statement... show more My topic: Money in sports

The thesis I came up with is:
Money invested in most major professional sports is excessive and it would be better to use that money for other purposes.

I'm afraid that my topic seems to broad, is it?
And if it is could someone please give me an example of a good thesis statement about 'Money in Sports'

Thanks
Update: It's a research essay and I plan on writing about player wages, leagues, clubs etc.
So should I make my thesis reflect more about what I'm talking about or is it fine like as it is?
