Universal Basic Income ALREADY exists (Ad)

Robert Kiyosaki, author of Rich Dad Poor Dad, says you don't have to wait for Elon Musk's vision of universal basic income. His Patriot Income Plan - funded by 14 partnerships controlling America's critical oil and gas infrastructure - already pays 10% a year with 42 payouts annually. Some investors are already collecting $4,800 a month. One has built income up to $25,000 a month. These partnerships have averaged 20% annual gains since 2020, with no U.S. tax dollars involved. The next payout drops in days.tc pixel

The comeback story of the century (ticker inside) (Ad)

In 2013, this struggling PC maker went private amid skepticism from Forbes and the New York Times. Instead of fading, it transformed into what the Wall Street Journal called a globe-straddling AI supercomputer builder. The company has drawn attention from both Elon Musk and President Trump, who awarded it a five-year, 9.7 billion dollar Pentagon contract. Louis Navellier's system recently assigned it an A rating, the same grade given to Comfort Systems, Supermicro, and Applovin before their historic runs. Louis believes a major event on August 6 could bring new attention to this company's role in AI infrastructure.tc pixel
