That's one way to look at it. On the other hand look at concepts like the 40 hour work week, weekends, bank holidays, the ability to take sick days and vacations, workplace safety, safe public transportation, job security, and so many things we take for granted due to collective bargaining.
And it's not just for the wellbeing of workers, but everyone. Look at the recent ban of ebikes on the London commuter rails over fire concerns. That wasn't brought on by forward thinking bosses or a campaign led by concerned citizens, no it was brought on by the rail transport union who understood the danger it posed and threatened to strike if the danger wasn't addressed.
Unions make life better for everyone. You can say but what about... Go ahead. Any human organisation is going to involve corruption, but the benefits and advances achieved through collective effort of unions shouldn't be discounted for individual failings.
Instead, that we can identify and call out the corrupt is something that would be impossible if everyone remained divided by business owners who aren't going to really go out of their way to treat workers decently if it might interfere with profits and the expectations of investors. The UK isn't like America where Elon Musk, Mark Zuckerberg, and other anti-union billionaires buy politicians and manipulate elections. Okay, maybe FB manipulated the Brexit vote, and Musk has ambitions in Farage and Robinson, but they say they're just average blokes making the world a better place. How's that working out for you?
Yes, there are some forward thinking capitalists like Rowntree who suspected that looking out for the welfare of working people was actually more profitable. We're amazingly fortunate this rare genius of capitalism took the time to verify and document his suspicions through scientific observation which he published. His treatise on the working poor not only led to better candy, but inspired Churchill to propose the establishment of a welfare system. Unfortunately, for every Rowntree there's countless other capitalists who'd blindly resort to slavery, mass murder, and any depravity if they thought it might add a few bob to quarterly earnings.
And you don't have to look far to find corrupt business men or for that matter slave drivers even today. The UK is hugely reliant on slavery in the twenty first century. Even more than the 18th century before Clarkson and Sharp started the abolitionist movement.
The only difference is that most slaves in the UK today aren't "illegals" but British citizens and the even vaster networks of worldwide slavery is obscured in a subterfuge of shell corporations, subcontracting, and other tricks of the spreadsheet that enables us to not really consider where all the shiny neat stuff we identify as trophies of modern civilization really comes from.
So go ahead and slag unions and vote reform, but you might want to consider the devil you should know than the easy rare example demons your average one percenter want you to despise instead of seeing how unions and government oversight might benefit you.
I'm sure they'll tell you their wealth is meritocracy in action and they aren't doing evil. It's nothing personal, just business. You understand. Right?
The world is a complex place. Humans are easy to corrupt, but the systems we've developed tend to work. But everything good requires work. Honest work. That's the hard part, but it beats the alternative.
