Should we have Universal Basic Income?

Universal Basic Income (UBI) is a policy proposal for regular, unconditional cash payments to all individuals (or adults) in a society, regardless of income, employment, or need. Whether "we should have" it is debated among economists, policymakers, philosophers, and the public—there's no consensus, as it involves trade-offs in economics, ethics, incentives, and feasibility. I'll outline the key arguments, evidence from experiments, costs/funding issues, and considerations to help you form your own view.
