Not "less than honorably." Illegally. What happened to your intense concern for the rule of law? Oh right, that was complete rubbish.
"But The Times’s investigation, based on a vast trove of confidential tax returns and financial records, reveals that Mr. Trump received the equivalent today of at least $413 million from his father’s real estate empire, starting when he was a toddler and continuing to this day.
Much of this money came to Mr. Trump because he helped his parents dodge taxes. He and his siblings set up a sham corporation to disguise millions of dollars in gifts from their parents, records and interviews show. Records indicate that Mr. Trump helped his father take improper tax deductions worth millions more. He also helped formulate a strategy to undervalue his parents’ real estate holdings by hundreds of millions of dollars on tax returns, sharply reducing the tax bill when those properties were transferred to him and his siblings."
At least $413 million, obtained almost entirely tax-free thanks to extensive tax fraud. Seed money? Oh brother. Well, grifters like Trump need gullible marks like you, so well done I guess.
He got all of his money from his dad. Competent people invested it for him to make him more money, and that is the story of Trump. He's nothing more than an idiot trust fund kid pretending to be a business man. Every time he has actually tried to run a business, he has failed.
