Musk Warns. Trump Acts. Your Retirement May Depend on It (Ad)

With Donald Trump back in the White House, many believe an economic revival could be underway — but it also brings new risks for retirement savers. Traditional 401(k)s and IRAs may leave investors more exposed than they realize. That’s why a Trump-backed IRS strategy is gaining attention. It allows everyday Americans to reposition their retirement savings into real assets like gold and silver — offering both protection and potential upside. A new 2025 Wealth Protection Guide explains exactly how it works.tc pixel
