These reports discuss state-level minimum wage increases, while pointing out that the federal minimum wage is still stuck at 7.25, same as it’s been since 2009.
The reports you linked do highlight a 9% wage growth between 2019-2022 for the lowest earners. I’m glad that they got that bump, but we’re very generously talking $10/hr here, and that is simply not a living wage in any part of America anymore. When factoring in change over time since the 70s, this is drops in the bucket and wages are still comparatively stagnant vs productivity in that time frame.
Also, this was during a time when companies were absolutely desperate to employ “essential workers” to keep operations going during the pandemic. I’d argue that was a much bigger motivating factor for this meager gains in the lowest wage brackets, and it had little or nothing to do with Biden’s policies.
