Donald Trump, the 45th President of the United States, has accumulated his wealth through a variety of ways. While many know him for his career in politics, Trump was making headlines in the business world for decades before entering the political sphere. 1. Real Estate: His primary source of wealth has been real estate. In 1971, he took over his father's real estate firm, Elizabeth Trump & Son, and renamed it The Trump Organization. He focused on developing and branding large building projects in Manhattan, including Trump Tower, Trump International Hotel and Tower, and Trump World Tower. 2. Television and Entertainment: Trump also had a career in the entertainment industry. He is known for his successful reality TV show "The Apprentice," which aired from 2004 to 2015. The show gave Trump an annual income in the multi-million dollar range. 3. Licensing Deals and Endorsements: The Trump name has been licensed for a vast variety of products and services resulting in substantial income. These licensing deals included everything from hotels and golf courses to clothing, steaks, and education courses at the failed Trump University. 4. Investments: Outside of real estate, Trump has made investments in stocks, mutual funds, and hedge funds. Heavy debts and several bankruptcies have also been part of Trump's financial history. His companies declared bankruptcy six times between 1991 and 2009 due to inability to meet necessary payments and to re-negotiate debt with banks, owners of stock and bonds, and various small businesses. This is a simplified overview, Trump's finances are complex and have been the subject of ongoing scrutiny and legal proceedings. Many aspects are private and not publicly disclosed as they might be in the case of public figures not involved in private business.
