This is why I can't take any anti-immigration sentiments seriously in this country. An american founded company runs a business for 20 years, sells it off overseas, and the new owners kick all Americans out of the equation.
Response from America: "well that's just business, I guess". It was never about preserving American labor.
If the company was profitable they wouldn't have needed to sell. It was always living on borrowed time. If a US owner bought it they'd have done exactly the same thing (layoffs) albeit possibly with new jobs in a different state than country.
