What tech companies?
At the end of the day, it's all about capital and IP.
American domiciled VCs and companies can outinvest just about any other competitor, and much of the core IP for vast swathes of critical next-gen technologies (high NA EUV, Foundation Models, Quantum Computing) is in the US, but American companies are fine transferring technology abroad (often with American government backing [3][4]) and moving jobs abroad.
China has a similar ecosystem but prefers to invest domestically and for IP to remain within China.
Meanwhile Japan, Taiwan, and Korea continue to back the US no matter what due to tensions with China and North Korea along with existing fixed asset investments in the US.
When companies like Amazon, Alphabet, Microsoft, and others are able to invest tens of billions of dollars in India [0], Poland [1], Israel [2], Portugal [5], Ireland [6], and others it makes them more open to collaborate with American capital and IP instead of dealing with alternatives who cannot deploy similar amounts of capital and transfer IP.
