Could be, but Trump also has five kids, and much more deterioration in the US economy could spell the end of most of his wealth. He might decide that the latter phase of his active life would be best spent reversing some of the deterioration. I guess it will depend on what his primary motivations are at this stage of his life.
Reality 101. Trump is not running for president, but his “media presence” gives some great advantages as shown in the original posting.
He is way too smart to seriously run.
