US President Joe Biden has signed an executive order aimed at promoting fair competition in the US economy, targeting industries such as Big Tech, Big Pharma, and Big Ag. The order has 72 specific items and encourages government agencies to use their existing authority to address corporate concentration. The move has been praised by some Democrats and rural groups, but criticized by big business and libertarian commentators. The order's effectiveness will depend on its implementation and the willingness of government agencies to follow through on its directives.
