I thought I heard you calling me :)
You asked "What does Health insurance have to do with your job?"
Well, everything, maybe you should ask the miner who was dragged out of the mine in West Virginia. People often engage in hazardous and dangerous jobs, which they couldn't otherwise do if not for health insurance. Health and job related injuries are very intimately connected as people are very often injured on the job.
you said "If you can make Wal-Mart pay for health insurance, why not make them pay for your car insurance as well?"
Well if you were using a company car they would have be responsible or if you were on the job while driving they might just have to. Lets say you were a race car driver and you were sponsored by a company, they probably would be responsible for paying your car insurance.
you said "How about if Wal-Mart also pays your homeowners insurance too?"
If you work from home then that might not be a bad idea to get them to do so but as most Wal-Mart employees actually work at Wal-Mart they only have to have insurance for the store itself :)
you said "If you hire a maid to clean your house do you have to pay her insurance and electric bill?"
Just because one is paying for a service does not mean that they are ones employer. For instance if I go buy a hot dog I'm not the employer of the hotdog vender, I'm just making a purchase. Same with a maid, if you are not running a maid service and are only purchasing a service then you are just buying the proverbial hot dog from the maid and are not her employer. However if the maid were a part of a business you were running then yes you would have to pay for her/his health insurance.
you said "Where does this slippery sloap end?"
I don't see a slippery slope at all, I see only the attempt to provide people with health insurance rather than allowing businesses, as they have been doing, to hire temps and avoid at all costs paying insurance. Not only do I not see a slippery slope, I don't see a slope at all.
