Irish-American presence in boxing if they kept getting marginalized forever?

Imagine a dystopian world where, unlike some other immigrant groups, Irish-Americans never get integrated into American society at all.

Long after the waves of Italian, Eastern European, Hispanic, and Asian immigration gain various degrees of acceptance in America -- after the Civil Rights movement, after the Obergefell decision, even after Biden's presidency -- Irish Americans are still treated basically as they were in the 1880s.

Unlike every other group in America, the constitutional Equal Protection clause doesn't legally apply Irish-Americans. Many businesses openly and explicitly won't hire them because of their Irishness. They are uniquely excluded from various social institutions. Kennedy is never elected. Well into the 21st century, late night comedy focuses on insulting Irish-American stereotypes as the safest type of humor.

Irish-Americans are kept at the 1880s level of marginalization for 140+ years. They remain one of the poorest ethnic groups in America for the entirety of this period. To add further injury to insult, special provisions in most states' welfare laws pay out only a fraction of their regular allotment to Irish-American welfare recipients. As of 2022, Irish-Americans are largely confined to inner city enclaves exclusively occupied by other Irish-Americans. Such political power as they possess remains in the hands of a few unimportant, largely unhelpful political machines in larger cities.

Now, then:

How would Irish-Americans perform in boxing throughout this period?

 

US bad! Irish not happy. Irish sad!

Irish box good?

 

I see. I see. Good Dempsey boxer. CT like.

Not like Irish Tunney boxer. Tunney boxer huggy man. Not stand. Not fight. Bad huggy man.

 

Yes. Huggy man use big brain. Little man always have big brain. Except Satterfield. Satterfield punchy man. CT like Satterfield.

Perfect fight be two Satterfields. Greggains ref.

 

That good point.

Best fight when Foreman fight Zaire heavy bag. Bag good. Bag not tax CT brain to understand fight. Bag know job to get hit. Wham! Wham! Wham!

Not like Ali. Ali bad boxer. Ali not let Foreman hit him. Young worse.

...Lyle good, tho.

 

So...now that we've driven off all but the tiny minority who appreciate both our sense of humor and my overly pedantic wall of text, do you think Irish-Americans would have continued producing lots of great fighters if they'd remained a poor underclass throughout the 20th and 21st centuries?
