What are the effects of poverty, begging, emigration, and inequality on development?

Development, in the context of a nation, is the growth and improvement to provide social and economic stability, and it is fueled by the activities within a country.
Poverty is the condition where individuals have insufficient resources to provide for some, if not all, of their basic human needs. Poverty has the attendant ills of sickness, ignorance, and crime. An unhealthy population cannot attain optimum productivity; a culture of ignorance shuns education and continues the cycle of poverty. Crime damages a nation's international reputation, fosters corruption, and contributes to the deaths of members of the workforce.
People resort to begging for different reasons—often to supply for their most basic needs. One reason may be civil unrest or war, which can cause disruption and displacement, leaving many destitute. Extreme food shortages and poverty may motivate others to beg. Left alone, beggars cannot contribute to economic development. Rehabilitation and social intervention must take place to assimilate or re-assimilate beggars into the labor force and fuel development.
Emigration also has a negative effect on development. Most emigrants leave in search of better opportunities, with no intent to return. Brain drain, the emigration of educated or skilled members of the labor force, has an even worse effect because individuals who receive tertiary education in their homeland, whose talent could have contributed to national development, use their education and talents overseas.
Inequality limits opportunities and privileges to a group or groups based on race, religion, economic standing, or social status. Inequality may lead to civil unrest, poverty, begging and emigration. Inequality is counter to development.
