Organized labor has introduced customs that you benefit from and take for granted.
All you have to do is look at the difference in quality of life that came before and after the changes we obtained from organized labor in the 1800s/early 1900s.
Most people don't appreciate the extreme asymmetry between those who control capital and those who create the wealth of nations (26 individuals have the same worth as 3.5 Billion individuals)
In fact, just look at the quality of life of a worker in a place with strong labor (say most of the EU) vs say, the US.
