Oh, please pay attention. It isn't 2.2% - it's gone down to 2.0%. And as for S&P 500 funds, the S&P is trading at a P/E ratio of 27 suggesting it's seriously overpriced, and it is heavily invested in a very narrow range of tech companies. NVIDIA 7.2%, Apple 6.7%, Microsoft 6.2% are the top three holdings. NVIDIA's P/E ratio is 68.6, Apple's 36.8, and Microsoft 34.7. The level of growth implied by these figures is almost certainly unobtainable.
And finally there's the foreign exchange risk. So, whilst the S&P has done very well over the last few years, there's no reason to assume that that level of performance will continue, and plenty of reasons to assume it won't.
