I saw the following sentence on this page: https://www.inc.com/video/minda-zetlin/4-habits-that-helped-make-warren-buffett-a-billionaire.html
4 Habits That Helped Make Warren Buffett a Billionaire
helped make a form of subjunctive or it is modal? I am confused by the form help + infinitive make. Why it is not made?
Based on what I read, a subjunctive is used in not necessarily factual information. So I am confused because the sentence feels like Warren Buffett is already a billionaire. Why is it not
Thanks for any help.
