What I wrote was essentially:

• Economic management: When you look across countries and time, centre-left governments don’t systematically do better or worse at running the economy than centre-right ones. Growth, inflation, employment—these indicators don’t show a consistent partisan advantage.

• Social outcomes: Where centre-left governments do show clearer effects is in social policy. They tend to reduce inequality, expand access to healthcare and education, strengthen labour protections, and improve measures of social well-being.

So your recap—“no more and no less successful at managing the economy, but they improve a variety of social metrics”—is accurate.

Would you like me to flesh this out with some comparative examples (e.g. Nordic countries, UK, US, Latin America) so you can see how it plays out in practice?

You said:

**Social outcomes:** Where centre-left governments _do_ show clearer effects is in social policy. They tend to reduce inequality, expand access to healthcare and education, strengthen labour protections, and improve measures of social well-being.

So are you saying that such improvements have no long term positive economic effect? A better educated, healthier population etc. has no long term positive economic effect?

Good question. To clarify:

Improvements in health, education, and equality do have long-term positive economic effects — healthier and better educated populations tend to be more productive, adaptable, and innovative. Lower inequality can also stabilize demand and reduce the costs of social conflict.

What I meant in the earlier framing was more narrow: when political scientists and economists do short- to medium-term comparisons (say 4–10 years, one or two electoral cycles), centre-left vs. centre-right governments don’t show a strong, consistent difference in headline economic metrics like GDP growth or unemployment.

But if you zoom out further — decades, generational timescales — the social investments often associated with centre-left governance can create the conditions for more resilient, inclusive, and sustainable economic performance.

So in short:

• Short run: economic indicators look similar across left and right.

• Long run: the social gains (education, health, equality) usually spill over into economic strength, though the causal chain is slower and more diffuse.

Do you want me to lay out the evidence for those long-run effects (like studies linking inequality reduction and education investment to productivity growth)?

You said:

Yes

Absolutely, improvements in education, health, and inequality can have profound long-term economic benefits. Here's a breakdown of the evidence supporting this:

📚 Education: Fuel for Innovation and Productivity

• Human Capital and Growth: Quality education enhances cognitive skills, which are strongly linked to long-term economic growth. Countries investing in education often experience advances in science, technology, and productivity .CSIS

• Returns on Investment: For every additional year of schooling, individuals can see a 10% increase in hourly earnings. On a national scale, this translates to higher innovation, stronger institutions, and greater social cohesion .World Bank

• Case Study – New Orleans: Post-Hurricane Katrina reforms transformed the city's education system, leading to significant gains in graduation rates, test scores, and college access .The Washington Post

🏥 Health: A Cornerstone of Economic Stability

• Productivity Gains: Investing in health care not only improves life expectancy but also boosts productivity. A healthier workforce is more efficient and less prone to illness-related absenteeism .World Bank

• Economic Impact: In the U.S., addressing health inequities could add approximately $2.8 trillion to GDP by 2040, highlighting the economic value of a healthy population .Deloitte Italia

• Global Perspective: The World Bank emphasizes that universal health coverage is fundamental to ending poverty and fostering robust economies .World Bank

⚖️ Inequality: A Barrier to Sustainable Growth

• Growth Impediment: High levels of inequality can hinder economic growth by limiting access to education and opportunities for large segments of the population .NBER

• OECD Findings: A study found that a 1-point reduction in the Gini coefficient (a measure of income inequality) is associated with a 0.15% increase in annual GDP growth .Global Priorities Institute

• Global Consensus: The IMF warns that prolonged periods of slow economic growth can exacerbate inequality, suggesting that inclusive policies are crucial for long-term prosperity .IMF

🧠 The Bottom Line

While centre-left governments may not always outperform others in immediate economic indicators, their focus on education, health, and reducing inequality lays the foundation for sustained economic growth. These investments create a more productive, innovative, and cohesive society, which is essential for long-term prosperity.
