>without any access to any kind of aid, medical assistance or education even for their children

If their kids are born in the US, they're automatically American citizens, with the same medical and educational entitlements as any other American.

> It's generations and generations of people who will be eternal prey for anyone who want to exploit them.

No more than any other American.

> They will be and remain poor, without identity neither nationality for their children, who under such circumstances will never come to love their new country.

If they choose to hate America, that's certainly their prerogative. They certainly won't be the first anti-American Americans to ever exist - heck, half the country tried to secede before.

> They will never be heard because they will never have the right to vote

Until they turn 18, then they can vote.

> The only change for them would be to lose everything again when they are found and deported.

No one born in America can be deported, unless they choose to renounce their residency rights.

> I'm French and I am an immigrant in an Asian country.

No wonder you have such an inaccurate image of how American citizenship works.
