The poor in developed countries are still far more wealthy than the average citizen in a country like india. What the poor here really need is financial security, not just some benefits that they lose immediately as soon as they earn too much. There are already some small scale programs that incentivise them to save by matching their savings with additional $0.50 for every dollar saved.
In reality saving is the engine of the economy. Consumer debt only temporarily increases the GDP. Especially in the form of payday loans it is not only bad for the individual but terrible for the rest of the economy.
