In some cases, poverty is a choice. There will always be a small percentage of people who would rather live on welfare (or whatever social assistance is available) rather than work.
However, for the vast majority of people who find themselves impoverished there was no choice involved. Many people are unable to find work due to lack of skills; lack of ability; mental, emotional or physical challenges; lack of employment opportunities; and, many other reasons too numerous to list here.
Many of these people are trying to better their situation; but, run into additional barriers in the form of discrimination against the poor; lack of funds to attend interviews; inappropriate clothing for the workplace; and, other legitimate reasons that hold them back.
Poverty is usually not a choice.
