Uncapped unskilled immigration works great when you have jobs available, and early America had plenty of those. Coupled with zero entitlement programs it was a perfect recipe for growth.
Doesn't work so well now, it would put enormous pressure on social programs already near their breaking point, and drive unemployment sky high as unskilled jobs are diminishing. Crime would increase as poverty is positive correlated.
However, if you make it past that initial surge, the 2nd generation could provide an enormous boost to the economy as long as education was prioritized.
Compare to uncapped skilled immigration and it's a much higher risk.
Rome had more than one tier of member of society, (eg citizen and non citizens) you could tie social benefits to certain social performance expectations such as military service, length of residency. I am not advocating open boarders or a multi tier citizen status structure merely showing possible solutions.
