You are using the word "relative". I'd say the US has gradually become capital starved, our tax system is eating our seed corn. Our growth rates have been pathetic the last 40 years.

More capital is always better. It lowers the bar for investment. It increases productivity, allowing us to get more of the best jobs. The strong dollar is a sign of success.

And don't forget that reprinted profits aren't always revinested, lots of it is paid out to shareholders who consume some of them, creating demand.
