Poverty is not a disease, as Quarrelsome pointed out.
Poverty isn't even a constant, it's dynamic. People go in and out of poverty all the time.
We also don't know the correlation and the causation between poverty and various indicators such as IQ, achievements, etc. (are you poor because you have a low IQ or do you have a low IQ because you're poor? etc.)
On top of that, where do you draw the line for poverty? Is it the lowest 10%? 20%? 40%? What if the statistics change next year, and I go from 40% to 30%, am I allowed to have children this year? Are my children taken away from me?
Etc., etc.
You haven't thought this through, or as I said, you're a wonderful troll! :)
Here I mean things like appreciation of education, work, stability of families, etc.
What could we do to change these patterns? (Apart from the usual recipes like making schools better. FWIW I'm from a country which has one of the most equal distributions of both income and wealth, but even this does leave a lot of people quite unhappy.)
Besides this, I guess the next best investment is in refining democracy and its safeguards, as well as the actual government, so that:
a) lobbying by corporations and very rich and powerful individuals doesn't corrupt the system
b) the system is as efficient as possible (there's always going to be inefficiencies but you'd want most of the tax money to actually be used for what they're meant instead of administrative overhead)
More than that, there's not much we can do. After all, at some point we have to rely on free will :)
There exist lots of diseases known to medicine that can be cured, but people can still get reinfected even after a treatment.
Heck you might gain a bit of sympathy then so maybe it wouldn't be a completely bad thing...
Or the South Side of Chicago.
Doing quarantine does not kill the disease agent. That is not what quarantine is for. Quarantine is for preventing the further spread of the disease agent.
For killing the disease (agent) there is the immune system or drugs such as antibiotics or virostatic agents.
