No, they get paid much less now than before the shit hit the fan in 2008. And as someone who actually starved and was homeless while having a full time job with university degree (not the american B.S. degree, an actual science degree) don't give a fuck about these fat union asses who were getting $100K salaries and still complained.
I had no idea that assembly line workers were getting anything like $100k back then, let alone complaining about it.
I was not aware of that either. But with proper seniority they were, and they did complain when it became clear that it can't continue and they have to take 50% cut. Also I remember being surprised to learn that cleaning stuff at university was unionized and getting more than $30k a year, it was when postdocs were in $40-50K range. At least I knew I could leave stuff at work without worrying about it getting stolen.
I'm not against unions. That said, I've never belonged to one and I don't know the ins and outs of the American situation (or yours if you aren't American), but by and large I see unions as more protecting workers and getting them a fair deal.
I work for myself and earn about £35k. I've been in my profession over 30 years (architect) and I did 7 years at university. I hear what you're saying. Many professions are relatively underpaid, for most who practice in them, and that would for example include many academics, engineers and suchlike. So your complaint is valid of itself (albeit I'm guessing that the 'average' assembly line worker didn't get anything like $100k).
I myself do moan, sometimes, about what others get (mostly footballers) but as the years have gone by, I do it less and less. On the whole, there are probably only a minority of people in the world better off than me, either materially or financially or in several other ways. Sometimes I think that happiness is a lot about who one compares oneself to. To those that earn much better money I say, 'good luck to you', because it almost never adversely affects how much I myself earn. On the whole in fact, if organisations like unions can ensure that others get decent money, it's a good thing, for the society I'm in, even if it never means my earnings are going to be raised in turn. It's better than a race to the bottom. I accept that it can be irritating to hear about at dinner parties though and I am not saying I don't suffer from jealousy.
It has to be said that my wife also works, in a public sector (and therefore unionised) job and gets about £45k. So our total family income is about £80k (ie approximately the aforementioned $100k). But we both work hard for that, are both in our 50's (so very experienced at our jobs and have put in the years) and we are currently putting two kids through university and have all the usuals, including a big mortgage. I have to say that what we earn and what sort of lifestyle it buys us feels like enough, with our main 'sacrifices' being not having private healthcare, cable tv or newish cars.
One caveat would be that I had to stop paying into my private pension about 10 years ago because of the recession and losing my job along with 50+% of my profession, and my pension plan wasn't too luxury to begin with and plummeted during the recession. So when we retire, we'll be selling the house, downsizing radically, paying off the (interest-only) mortgage and using the leftovers (on top of my wife's pension) to help us through old age, if there are any leftovers. Lol. If I'm lucky with my health and can stay abreast of technology, I'll be working until I'm 70 and afterwards there won't be any cruises (I'm not much bothered though) and the NHS is creaking so I won't be counting on fab healthcare when I start to deteriorate.
Now, I don't know your predicament. You may be younger than me and not yet have gained a decent foothold on the property ladder and so on, so I'm not chiding you. You are probably underpaid in comparison to a section of your society.
