Ben Hall? Isn't he out on loan while having renewed his deal with Brighton for another year in 2018? He's most likely doing very well financially in comparison to what we could offer him, and he's still on the books of a Premiership club.
Matt Kennedy left St Johnstone because Everton came calling. Very few footballers worth their salt would turn down a move like that, unless they thought they weren't actually good enough of course. He signed on a three year deal, guaranteeing him three years of decent cash most likely, while allowing him to learn the game at a higher level. He then went to Cardiff on a 3 and a half year deal, where I doubt the wages were pocket change.
Now he's back in Scotland with St Johnstone, still only 24 years old, has a shitload more experience than he would have had if he hadn't left, and his bank account is probably healthier as well.
Than make money? Probably not. Last I checked I couldn't pay my mortgage or help put my kids through school on my reputation.
For some reason many football fans don't seem to realise that this is these guys jobs. It's what they do for a living. If a company came along to us in our job and offered us far more money to do the same job for them we'd be offski in a heartbeat. No nonsense about staying at the smaller company to "learn the trade" or to "build a reputation."
You're in the game to make money and win things, in that order most of the time. We see plenty of legends hawking their medals and trinkets to raise money for themselves, but very rarely do we see a retired multi-millionaire footballer crying into his versace pillowcase about not winning a few more Scottish cups or a league title.
You get in, make as much money as you can at the highest level possible before you're old and broken down and have to retire.
