There certainly are idiot MBAs (and non MBAs), and perhaps the ratio is too high in the USA, but based on the pre-eminent businesses in the USA, I wouldn't say it's "the" culture.
One of the reasons Intel failed and TSMC succeeded is because Intel was unwilling to pay what the other big tech companies were paying (and part of that pay is with RSUs which stock buybacks help offset). However, for workers in Taiwan, TSMC was the best option, so TSMC could pay less.
