In the context of inflation, the standard party line theses are like this. Right wing: inflation is caused by huge Government spending. Left wing: inflation is caused by a range of factors, and Government spending is just a minor one. The other ones are the supply chain, the emergence of the economy from a crisis, a spike in commodity prices, especially oil, some of which could be attributed to the hurricane Ida that resulted in lots of refineries being shut down, etc. About a month ago another idea was added to this list: inflation is caused by corporate greed. The problem with this idea is that corporate greed is not new. If corporate greed could cause inflation, it would have caused inflation 5 years ago, or 10, or whatever. The proponents of this idea claim that it's the market consolidation that lead to increased pricing power for the corporations, and there's some truth to this, but again, this consolidation did not experience any quantum leap recently.
I think on this topic, the Right wing is absolutely right, the inflation is without a doubt caused by the massive, unprecedented money printing. What they forget is that this money printing started during the previous administration, so there's that.
