What a silly lie.
Tax incentives and subsidies for their going abroad is what got them going abroad. Sure, production is cheaper, but building factories isn't, nor is transport.
Attempts to roll back those incentives have been rebuffed by the GOP, though I doubt the Dems were pushing THAT hard.
Oh, tax rates might be high for billionaires, but there's plenty of loopholes. The top 5% of the richest don't pay ANY taxes at all, and you'd be shocked with what the bigger corporations don't pay either.
Sheesh.
