A Chulalongkorn University political scientist warns Thailand's fiscal system risks collapse within a decade without urgent reform. Public debt is rising toward 80% of GDP (from 70%), with projections reaching 100% GDP within 5-6 years. Key challenges include overlapping government agencies, inefficient welfare distribution, and hidden state-owned institution debt. The government must restructure public sector spending, target welfare more strategically, and broaden the tax base rather than hastily raising VAT rates.
