Joe Biden got his 2024 presidential re-election campaign underway in Philadelphia on Saturday by continuing to pitch voters on his pro-labour bonafides. The Democrat told an audience of union members at the Philadelphia Convention Center he would keep trying to boost the working and middle class with “Bidenomics,” which he framed as opposed to the ideas of Republicans, who recently unveiled a series of tax proposals that would funnel benefits overwhelmingly to the wealthiest Americans. “They are coming for your jobs. They are coming for your future. They are coming for the future we are building for your kids and grandkids,” Mr Biden told the crowd. “And when they come as they did this past week with the trickle down economics plan, cut taxes for the rich, who do you think they are carrying the water for?...Who do you think is going to start carrying the burden? You are. Working people in this country.” According to an analysis from the Institute on Taxation and Economic Policy, under the recent tax proposals from the GOP, the richest fifth of Americans would receive $60.8bn in benefits next year, while the poorest would receive nearly 60 times less. During the event, Mr Biden cited initiatives like the bipartisan $50bn semiconductor manufacturing investment bill signed last summer, as evidence of his attempts to back American workers. This is a breaking news story and will be updated with new information.
