Which conditions most likely account for extreme poverty and economic disparity in Southeast Asia?

scarcity of natural resources to support farming and industry
lack of interest in trade and commercial partnerships
isolationism that limits exposure to modern technologies
competition among workers for too few jobs and low wages

Competition among workers for too few jobs and low wages is most likely to account for extreme poverty and economic disparity in Southeast Asia. This can lead to a lack of job opportunities, low wages, and a cycle of poverty that is difficult to break out of. Additionally, scarcity of natural resources to support farming and industry can also contribute to economic challenges in the region.
