In AUS/NZ you're not going to earn even close to the same amount as you would in the US. Every time I've changed jobs, it was for an extra 100k+ per year. The rec room/pool table can't compete with that.
My current manager has been with the company for almost 20 years. He doesn't feel the need to leave because his stock options have made him a multimillionaire. The company doesn't care about him or me, but we're both happy to stay because we don't need them to. We just need them to pay us.
