You're not clearing any misconceptions, you're making them. It would take a lot of research and work to discover what a "good district" is, while in western Europe you can just send your kids to school and not worry about it. Lots of states don't have any good districts at all.
Healthcare paid for by the company is the stupidest thing ever. The company is trying to save money and having them pay for health care means (a) you have little or no choice of what provider they choose and (b) you cannot be without a job ever due to the insane exposure that would put you and your family under and keeping the insurance plan you had with your employer will usually be prohibitively expensive.
Many employers just give you "catastrophic" coverage which will leave you with something like a $10k deductible (I'm serious) and if you do manage to go over that expect to take the company to court for not paying. Anecdotal but I only know two people who tested this (I'm one of them) and in both cases the insurance companies refused to pay. I sued them to get my bills paid. The other guy wasn't so lucky. Shame, he would have retired by 40 if it weren't for a surprise illness.
You can't "always" take non paid vacation. In many companies if you do that make sure you take all your stuff with you and polish your resume before you leave.
2x the salary? Not where I live. I'm above all but a Facebook/Google salary (but those are within view) and I don't know what 3/4 the social benefits you're talking about are. The US has worse roads, hostile public services (e.g. DMV, police, etc.), a horrible health care system and poor worker protections (compared to Europe). Could you break down your social benefits because I literally cannot imagine what you could possibly mean with this.
