Good investing has never been about X will make a lot of money, buy X. It's about what price are you buying the money that X will make. Right now, a lot of future money US will make is baked into the price of those US companies. You'll pay $100 for $4 of US earnings or $8 of UK/Japan/Netherlands/Canada/Sweden/etc. earnings. People already expect US earnings growth to be almost double. The question is do you think it will outpace even that? Even if you think US earnings growth will be somewhat better than the rest of developed economies, it's a worse investment. For example, developed economies index, VEA, outperformed US, VTI, last year.
