Most medium-to-large employers in the US are self-insured, although big insurers manage the plans for them. When I was working at a factory with a couple of thousand employees, one of them crushed her leg in a motorcycle accident and required a total amputation. Shortly thereafter (and before her return to work) we had an all-hands meeting where they emphasized the importance of vehicular safety during our off hours. HR didn't name any names, although everybody knew who they were talking about.

My company has about 1,000 employees and underwrites its own insurance. They allocate a pool at the beginning of the year and anything that isn't used is written off as profit at the end of the year. I don't know anything more specific than that, but our medium sized, successful company does do this.

Isn't this usually coupled with some sort of insurance that covers a major cost overrun? That secondary insurance might get skyrocket if it gets hit repeatedly.

There was that blow-up a few years ago when the AOL CEO basically blamed an employee with a sick baby for the company's unprofitability. (And maybe that overstates what happened, I'm sure you can find the details if you want)

Family farms.

If you're concerned about family farms you would oppose things too like ag-gag laws regarding un-hygenic food production/abuse and the general anti-humane industrialization of food products both animal and other.

These are far more potent threats to traditional pastoral and agricultural traditions than tax policy. If it was just a bunch of family farms competing against each other (or more likely forming co-ops given history) then it might be a bit more of a fair playing field.
