u not specific about big companies' view on what...
in general big companies want to maximize profits. to do dat, they want to minimize costs which is why they move production to wherever has the lowest costs. sumtime it is here in the US but a lot of time, it is overseas which means less jobs in the US.
tax is another thing big companies try to avoid. so Apple keeps the $ they make in other countries over there instead of bringing it back. that way they dont pay tax on profits. they also are against customs n tariffs unless the fees are imposed on their competitions.
there are many other topics. plz feel free to ask 4 specifics in comments.
