You didn’t. All you did was point at what was said and show that we haven’t achieved perfection. So yeah. There was some bad with the good but the point is overall things are better.

This is poverty then vs now. I can pull up starvation, death by war, death to disease and life expectancy if you like. They all are not supporting your argument.
1970s: • Number in Poverty: Estimates suggest that in 1970, approximately 1.4 billion people lived in extreme poverty, defined as living on less than $1.90 per day (adjusted for inflation and purchasing power parity).  • Poverty Rate: This represented about 37% of the global population at that time. 
2020s: • Number in Poverty: As of 2020, the global extreme poverty rate was approximately 9.7%, with about 700 million people living on less than $2.15 per day.  • Poverty Rate: This indicates a significant decline from the 1970s, though progress has slowed in recent years due to various global challenges. 
And yes from ChatGPT.
Things have improved significantly in many areas since the 1970s, though challenges remain. Here are some notable ways the world is better today:
Technology and Connectivity • Computing Power: Personal computers, smartphones, and the internet have revolutionized how we work, learn, and communicate. • Global Connectivity: The internet allows instant communication and access to vast amounts of information, fostering collaboration and knowledge-sharing worldwide. • Medical Technology: Advances like MRI, robotic surgery, and telemedicine have improved diagnosis, treatment, and access to healthcare.
Healthcare and Longevity • Life Expectancy: Global life expectancy has increased due to advancements in medicine, vaccines, and public health initiatives. • Disease Control: Eradication of smallpox and better treatments for diseases like HIV/AIDS and cancer have saved millions of lives.
Social Progress • Civil Rights: Progress in gender equality, LGBTQ+ rights, and racial justice, although incomplete, has created more inclusive societies. • Global Awareness: Social movements and the internet have made people more aware of human rights and environmental issues.
Education • Access: Literacy rates have risen globally, and access to education has expanded, especially for girls and marginalized groups. • Digital Learning: Online education and tools have made learning more accessible and diverse.
Economic Development • Global Poverty Reduction: Extreme poverty rates have declined significantly due to economic growth and development programs. • Global Trade: International trade and technology have created interconnected economies, raising living standards in many regions.
Environmental Awareness • Clean Energy: Advancements in renewable energy technologies like solar and wind power offer cleaner alternatives to fossil fuels. • Global Efforts: International agreements like the Paris Accord aim to address climate change collaboratively.
Quality of Life • Convenience: Modern conveniences, from online shopping to ride-sharing apps, have simplified everyday life. • Entertainment: Streaming services, gaming, and digital content have diversified entertainment options.
While these advancements have brought significant benefits, ongoing issues like climate change, inequality, and mental health need continued attention.
Did you ever walk down the street the 70s it was all cigarettes, leaded gasoline and diesel. So what if Paris accords failed. It is still much better now.
