Once again, you're creating nonexistent false dilemmas.
#1. Your argument is the equivalent of claiming that a baller scoring 20ppg on 55% shooting is hurting the team because someone else on their team is scoring 22ppg on 58% shooting. Claiming that someone is not the absolute prime highest contributor is NOT calling them a net negative. Illegal immigrants do NOT bring down the "overall averages", they contribute far more than nonworking adults, seniors, criminals, prisoners, many wealthy tax dodgers, and a large number of parasitic corporations.
#2. Not that "overall averages" are a sensical standard anyway - no one's experience is determined by the "overall average" of the country. If someone else comes in and contributes positively to the system, others experience that as a net benefit. It makes no sense to claim that a net benefit to the system somehow degrades anyone else's experience - there's no way from a to b there.
#3. You keep comparing illegal immigrants to legal immigrants as if there is some choice in the system. Are you promoting a proposal to legalize the bulk of illegal immigrants, or to replace all illegal immigrants with a group of comparable legal immigrants? If so your question is relevant. But that's not the question being asked right now, the question is them or nothing at all. And they are a far better contributor to society than nothing at all.
Of course, I've said all this already and you've ignored it, repeating things that don't work logically or have already been disproven. I provided receipts and you completely ignored them. It gets tiring to have to explain the same principle three times and then have you continue on, it's like talking to a stone wall.
Honestly, what do you feel is the marginal utility of your time here? Do you feel like you're learning something? Do you feel like others are learning something from you? Why do you post if you don't take other people's arguments seriously and people don't respect your arguments?
p.s. - where did you come from? I legit don't remember you before the last couple weeks at all. Are you an alias for Napoleon meant to engage with people he put on ignore or not?
