The separation of church and state is vital for fair governance, but equally important is the separation of culture and state.
Focus on government’s role: to serve the people and their needs, especially for needs that aren’t met by private industry because there’s no profit in it, like roadways and the delivery of basic needs like water and safe housing, and basic education systems, and healthcare, to name a few.
Government shouldn’t be focused on preserving culture – that’s the job of society at large, and museums, and restaurants, and individuals. Culture comes and goes, and it’s all very personal and emotional, but no one culture is better than another.
But the needs of people of all cultures are common. We all need food and education and safe harbor and healthcare systems and care systems for those who can’t care for themselves. These needs are common, blind to political boundaries.
A government should never say, “My country first!” Instead, it should be asking, “What do my people need?”
And the richest of countries? Assuming they are shouldering their responsibilities? Then they should ask “How can I help other countries?”
