In an idyllic world where no capitalist greed is focused on maximizing shareholder value that might be a more significant concern. But in modern day, a union raising their wages by 10% might result in less than a 1% increase in user prices. Whereas the ruling class of capitalists are the true source of greedflation making products unaffordable.

If anything in your example I would argue that the better solution is actually more unions. Those nail salon workers should also earn living wages to afford the goods, which unions would fight for. I would be shocked to learn of any case where a union could be compared to the average elite-class capitalist in terms of greed.

You seriously think high grocery costs are due to unions? How are you both pro-communism and anti-union?
