The evidence for supply chain issues - as you mention - and price gouging being contributory causes is much more convincing. If you are not convinced that price gouging is going on, consider profit levels in energy companies in recent months.
Please don't blame this on workers who if anything need to be paid more, and paying them more will not impact inflation, only make it easier to cope with. It may even bring inflation down if jobs in supply chains become more attractive and force profiteers to become more competitive.
