Based on your first reply and mentioning the strides taken over the years, I wasn't sure if there was any reason you listed two male character names before the female character name. That's all
As for our company's "number of reason's", I've stated that our internal practice is just that so those reviewing others work (check for accuracy and compliance) can quickly and easily follow the flow of income and expenses to each person, and then be sure any deductions/credits are properly allocated in the instances it's required to be. Keeping the practice uniform makes for better work flow.
I can't speak for other entities or companies and their practices, but if you're truly interested, you'd probably be best to ask them directly.
Flip a coin 100,000 times and you can expect that about 50,000 times that coin will land heads up. If you are betting on that coin flip, and the coin lands heads up 99,000 times out of 100,000, it is reasonable to suspect the game is rigged.
Take 100,000 organizations in the US that still choose the account holder by gender. You and I both know that I don’t need to interview anyone to find out that it is highly unlikely that 50,000 of these companies routinely treat the female in the relationship as prime. Actually, we would be hard pressed to find even one company in the US that does this. Can you name one? I can’t.
Is it logical to assume that almost 100,000 out of 100,000 firms have come up with perfectly justifiable reasons to automatically consider males, but not females, to be their prime clients? Logic can’t explain this. But history can.
US laws governing the rights of married women have a starting point, and that starting point came to us via English Common Law and the doctrine of Coverture. It stated that “the husband and wife are one person in law: that is, the very being or legal existence of the woman is suspended during the marriage.”
Women have been slowly and painfully chipping away at laws and customs that completely erased their identity upon marriage ever since the doctrine of Coverture was adopted into our early legal system. (I described in an earlier post that some of these directly affected me in my lifetime.) And the last remnants of these outmoded patterns even today can be found in organizations, like the op’s dental office, that obstinately insist that a man, instead of the insured, must be the prime member in a team.
I can actually see how, in your company’s case, you have a better reason to do this many others. You’re dealing with the IRS, which was founded prior to a time when most married women didn’t work. The husband was almost certainly the one and only breadwinner. It probably makes it much easier for your company to continue this pattern than it would be to ask each couple who wishes to consistently remain Taxpayer #1 and who wishes to remain Taxpayer #2 in your records. But it’s history, not logic, that determines that a married female breadwinner in 2022 is Taxpayer # 2 in your records, while her husband who stays home with the kids is Taxpayer #1.
So please don’t ask me to explain why I don’t care which cartoon character is named first on the disboards, or whose name is signed first on a birthday card, but I do care that I feel the weight of history slowly receding. To seriously ask me why these are not equivalent issues is to prove my point. We are not quite done yet.
