Talent in Australia etc is just as awesome and doesn't burn itself out while being productive. Having sane and "fair" working conditions goes a long way.
I was having a conversation with a senior director about 5 years ago about why not opening an office in Sydney. Plus points being high levels of professionalism and reasonable TC (stock comp being unheard off at the time). His retort was well if stock is not there people won't be incentivized. For folks talking about meaning and impact I was shocked how he couldn't fathom the idea that may be people just wanna do an honest day's work for an honest day's pay! Oh well
