This sounds like a bad idea for everyone, including Taiwanese who will be paid lower salaries, or denied raises, because the company can hire a foreigner for that amount of money--so why would most Taiwanese boses pay more to the "cheap" labor?
Maybe some office jobs will open up, but who's going to be lining up to work in a Taiwanese office for 45 large--or less? I'm sure there is a small segment of us out there for whom this might be okay, but not many.
And once a foreigner's starting salary is lowered in one industry, why not in another?
It's just going to get worse out there.
