This man fails at everything.
https://www.youtube.com/watch?v=voxXDDq58BkTrump University (2005–2010): A for-profit "education" company that promised to teach students real estate secrets. It faced multiple lawsuits from students who claimed it was a scam and involved aggressive upselling. The business shut down, and Trump eventually settled a fraud lawsuit for $$25 million.
Trump Airlines (1989–1992): Trump purchased the Eastern Air Shuttle to create a high-end airline experience. Burdened with heavy debt, it struggled financially and was ultimately turned over to creditors.
Trump Vodka (2006–2011): Launched with high promotional fanfare, this brand failed to compete in a crowded market and was eventually discontinued.
Trump Mortgage (2006–2007): Trump started a mortgage company just before the 2008 housing market crash. It collapsed in a little over a year due to poor management and a declining market.
GoTrump.com (2006–2007): A travel booking website designed to compete with sites like Expedia. It folded after only about a year in operation.
Trump Magazine (2007–2009): A luxury lifestyle magazine that struggled to attract advertisers and ceased publication after two years.
Trump Ice (2003): A line of Trump-branded bottled water that quietly faded out of the market due to low impact.
Tour de Trump (1989–1990): A cycling race aimed at being the American equivalent to the Tour de France. Trump withdrew his sponsorship after just two years
I don't even like trump, but I am not delusional.
Edit: I guess learning from mistakes is a foreign concept to people like you.
