That's taking something that happened about a century ago and using it as an argument for the current situation.

If you're looking for something much closer to home, look at how in the past half century unionized corporations were forced to take over pensions, and how they're doing now because of this. Pensions are a financial product, which should be paid for by each employee - quite likely with supervision and safety net from the state. Putting it on the employer's tab turned out to be more or less giving away the future of the company. And that's pretty much 100% on the unions.
