Yes, the Wall Street Journal was correct in their criticism of Mr. Trump's Carrier deal. As they pointed out, forcing the company to stay in the United States is not going to guarantee jobs long-term. If the company cannot compete in the market due to the costs associated with doing business in the U.S., then jobs will disappear anyway.
Surprisingly, a mainstream media outlet, the Wall Street Journal, has reported accurately on the Trump/Carrier deal. While Mr. Trump claims (via his Twitter account) that he is saving America by keeping carrier in the U.S., what he hasn't mentioned is that he used tax payer dollars to do so. Anyone can go to a company, hand them money from the taxpayers, and say "please stay here and do business". This is all that Mr. Trump did. Very little delegation was involved. The WSJ reported it how it happened, and their criticism was absolutely correct. If Trump is willing to hand out insults, he should be able to take them when he makes poor choices.
Yes, the WSJ was correct in its depiction of what really happened during the Carrier deal. Trump always inflates his accomplishments, lying about them and making them look more impressive than they really are. The Wall Street Journal is not going to get blinded by his self-aggrandizement. They will call things out the way they really are.
Yes, the editorial board of the Wall Street Journal was correct in their criticism of Mr. Trump's deal to keep jobs with Carrier in Indiana in exchange for tax incentives and benefits. His deal sets an example that all companies need to do to get these benefits is threaten to leave the country.
