Just a factual example, in Sweden this year the union agreed wage increase for IT workers was 3.5% against an almost 10% inflation year-on-year and almost everyone is unionised. In an unionised sector in the US this would have been cause for immediate strikes.
In Sweden (and many other european countries) unions work with government and companies to make the business succeed and that success be spread to the employees, this means the bad times are also amortised by the workers as well.
It is not perfect but it is not a zero-sum game which keeps both sides more aligned. I wish I could have had a 10% raise to match inflation, but I have been getting ~1% raises above inflation for the past several years so it kinda makes up for it.
