Exactly.
If you eliminate the seniority system within a company, and base advancement on merit, you introduce a whole lot of potential for abuse into the system. You get management that plays favorites, Chief Pilots who may not like you, vice presidents that want to get their Sister-in-law a good job. Politics, favoritism, cronyism, nepotism. It goes on and on.
I agree that the universal seniority likely wouldn't work. That's why I think you have to ditch it and start over.
The merit system works pretty much in other areas of business. It's interesting that your objections are the same ones levied by teachers against a merit system. Any system will have its flaws. Don't let the perfect be the enemy of the good, or whatever that saying is. I can't imagine you wouldn't be able to put in safeguards to prevent the worst abuses. Moreover, if a company allowed that to happen, then pilots likely wouldn't want to work there.
It just seems to me, as an outsider, that seniority has so many downsides, the biggest of which is that it makes pilots virtually indentured servants. To wit, when I went to SimCom last year, my CFI was on furlough from Spirit. He had too much seniority to risk taking another job, so he was working for peanuts and brown-bagging lunch hoping to get back on with Spirit. If he had, say, enough hours to be Senior Vice Pilot under my plan, he could apply to any other airline and not sweat the seniority.
AAhh, but I hear you thinking, that's not fair, because there are guys already at the other airline toiling the Asst Sr Pilot level that this guy is going to jump over. Well, that's true. If there aren't enough openings, they may have to jump ship to another airline in order to advance, or keep building hours until they too meet the Senior Vice Pilot standards. That's how things work in, say, finance.
I dunno. Again, it just seems that there has to be a better way. Furlough just doesn't make sense to me. ALPA might not care because (I'm guessing here) furloughed pilots still pay union dues, so the incentive isn't there to get them in the air. I might be wrong there, and I hope I am. I would, if I were ALPA, suspend dues for furloughees.
