(EDIT - to answer Klue's question...)
I worked for a company, and I now work for another company. I decided a while back I'd had enough of my career. So I worked at swapping and eventually found someone who was willing to take a punt.
I went in as a junior. I knew I was throwing away good money, and it would be years before I saw good money again (assuming I made it!). So when it came to negotiations for my new job I aimed high. Turns out not high enough. This new employer values good employees. Like most smart employers. He countered my offer and said he could do better.
Do you think your boss always drove a new car? He went straight from school to owning dozens of properties? Or did he have to work for it? Did he do his time on $9 an hour? Put his money, his family on the line? Risk bankruptcy, a downturn in the economy? I'm guessing before you clock on he's working, and when you clock off he's working. I know my boss is, and I work long hours.
That guy giving you your job has a hell of a lot more riding on your job that you do (you said it yourself, 5 times the profit). Hate to shock you, but we all work for profit, sadly not always ourselves.
On any given day in my last job I could save my boss $5K because I was good at what I did. Do you reckon I was getting $5k a day? Don't think so.
Unions HAD their place. A lot of what all workers enjoy now was won by unions back in the day, but the world has changed, and sadly for many unions so has their relevance. And I'll also say the stereotypical building unions don't do the pro-union movement much service. I've seen first hand how the fuck over non-union businesses, I've personally seen non-union tradies threatened. I've personally seen sites shut down because there was less than 3/4 coffee in the jar (and just to clarify, I saw all this because I worked directly next to a building site for a while and we shared common space, and I got to know a lot of the guys, including the union site reps quite well.
The day everyone was supposed to go to the MCG? It happened to tie in perfectly with a RDO, long weekend and 'family picnic day', no wonder no one showed up, they weren't even interested when a 5 day weekend was available.
