Actually, only 16~17% of Pennsylvania's workforce is represented by organized labor. (Source) As with most other states, membership is probably heavily skewed toward government employees and teacher's unions, at 40+%. And while Pennsylvania's steel and mineworkers had a national reputation for the strength of their unions, that was before you were born, and their influence has been long in decline. It is doubtful that Pennsylvania's manufacturing sector is hampered by union membership anymore than the 15% national average. You really should become more acquainted with the facts rather than spreading misinformation.
