As public finances worsen, few areas of government spending are likely to escape close scrutiny. Education, which accounted for 13.3% of public spending in OECD countries in 2006, now faces some lean years. Pay rises for teachers may be off the agenda; school class sizes are unlikely to keep falling; decrepit buildings may have to serve a few more years. Countries where the taxpayer funds higher education may have to ask students to part-finance their tuition, or else see their campuses crumble and become more crowded, and their professors flee abroad in search of higher pay. In some rich countries, such as France and Sweden, the share of public spending going to education was falling even before the economic crisis.
