Perhaps because the inputs to domestic manufacturing are currently more expensive. Actually increasing manufacturing capacity first requires construction and capital expenditure. I'm not sure how those metrics are doing.

Because factory machines and raw materials are being tariffed. Also because a source of cheap labor (immigrants) is being excised.

It certainly does. And companies are rightfully hesitant to invest, because the legally dubious basis for the tariffs may not survive this month, much less into the next administration.
