Why are Singapore and Ireland similar?

A lot of U.S. IT and industrial companies have European HQ in Ireland and Asian HQ in Singapore, And Why are Singapore and Ireland similar?

Historically, both Singapore (Singapura, 新加坡: Sir. Stamford Raffles, 1819 and 1965 ) and Ireland (Éire, Éirinn go Brách: An Ghaeilge, 1919) were colonized by the British Empire, which had a major impact on their political and economic development. This shared colonial past has influenced their present-day political structures, with both countries adopting parliamentary democracies that are based on the Westminster system.
Politically, both countries have experienced significant economic growth and development over the past few decades, with Singapore becoming a major financial center and Ireland attracting multinational corporations with its low corporate tax rates. This has helped to boost their economies and raise the standard of living for their citizens. Their economic success can be attributed to a combination of favorable government policies, a skilled workforce, modern infrastructure, and a focus on innovation and research.
However, their small land size and reliance on exports have also made them vulnerable to external economic shocks, as seen during the global financial crisis of 2008. Additionally, the high cost of living in both countries has led to concerns about income inequality and affordability.
Overall, while their colonial past and shared language have influenced their political development, Singapore and Ireland have taken different paths to achieve economic success and face their own unique challenges in the present day.
