One retailer's post says the prime minister "has never done a stocktake and somehow still gets 47 per cent of the business and takes zero risk."Startup founder Frank Greeff, who helped propel the social posts that have spread from the tech startup sector to small businesses, has admitted it prioritised attention over accuracy.Mr Greeff, who sold his real estate marketing company RealBase for $180 million in 2022, made multiple posts, including one that said: "Every Australian founder just got [a] new founder with 47 per cent equity."The photo included an AI image of Anthony Albanese, insinuating the government would be taxing every business owner at the highest marginal tax rate, plus the Medicare levy, as part of a sweep of reforms in last week's federal budget.In fact, the changes to CGT will mean that from July 1, 2027, Australia's 50 per cent CGT concession will be scrapped and capital gains will be taxed at a minimum of 30
