I don't know this author, but the arguments that increasing wages will cause inflation, independent of their economic accuracy, are also perfectly tuned messaging for a specific group, the owners of businesses (and the high-level managers). That could be coincidence, but if the beneficiaries are paying attention - and that group is very sophisticated politically - it's probably not.
Openly opposing wage increases for workers is political suicide, especially given the context of decades of flat wages and income inequality, and of the pandemic and essential workers, and given that it displays brazen greed and self-interest at the expense of the rest of the country.
But if they convince enough people - not everyone - that wage increases cause inflation, while they also stoke fear of it (remember during the Great Recession, fear of inflation was a tactic against Obama's policies), they can reduce the wages paid and keep more profit. It takes convincing people not directly affected by the issue, such as white collar workers who are already highly paid (ironically) and retirees, which IMHO is easy and often done. It also takes convincing people directly affected that their own wage increase somehow harms them, or that they should sacrifice for the country; that's harder, but as we've seen, many people vote against their economic self-interest and even risk theirs and their family's lives for political movements. Remember, they don't need to convince everyone, just enough people.
If inflation risks significant harm, and if wage increases are a significant factor (which I don't believe), I think suppressing wages is the last thing we should consider, if we consider it at all.
Imagine if they said, 'SV company pricing is causing inflation' or 'wages in SV are causing inflation'.
