I realize that this might be a bit off topic, but bear with me...
Several years ago, maybe around 1982, I was working for a company that had a union, of which I was a member. When contract came up for renewal, the company wanted to add a new twist: a small contribution by the union workers towards our health care costs. I believe it was around $10 a month. Well, most of the guys snickered and said yes, because our wage increase would easily cover this.
Imagine our faces when the next contract came up, and the company asked for an increase. All along the union members had never had a concern about negotiating a number for the company. They had only dealt with percent increase in wages. From that day forward, every contract centered on TWO factors instead of one: wage increase and insurance increase. It never went away.
That is why I can understand the voters feeling a bit queasy on this, because once those things exist, they never go away.
