Francis Crescia,
The results from the Trump tax breaks were mixed. Business Innovation and investment are driven by competition.
Trump will likely hold back Trump. But that is a dangerous way for Democrats to retain the presidency. In tennis, it would be winning by depending on your opponent to double-fault continually.
To win against Biden, Trump must display reasonableness to the undecided voters, which he may not be capable of. I discussed this in "Donald Trump the Town Hall Clown?" which remains relevant. I invite you also to read "Biden Needs Help to Win 2024," which also relates to your article.
Best.
