I don’t know why taxpayers should fund businesses, but admit it’s hard to build competitive industry in the USA if foreign countries are willing to cover the costs to build elsewhere.
In this particular case, you maybe want to look at where we are having to source chips for defense products from, from battle computers on tanks and ships down to the individual rifleman’s modern optical sight.
Hint: We *can’t* source most of them here in the States because there’s almost nobody that can provide them from US plants. The subsidy would also offset most of the government-caused overhead and regulatory compliance stupidity, as well as clearing regulatory roadblocks.
