Where is the most cost-effective global migration?

Among Southeast Asian countries, Singapore, Brunei and Malaysia are relatively rich, while other countries are average. Malaysian immigrants have a second home project. Under the age of 50, you can deposit RM 300,000 in the Malaysian bank on a regular basis, and applicants over the age of 50 can deposit RM 654.38+RM 05,000 in the Malaysian bank on a regular basis. Singapore can directly apply to become a permanent resident of Singapore as long as it invests S $2.5 million. Brunei is not an immigrant country. To sum up, Malaysia's second home project is more cost-effective.
