You hit it right on the head, retirement in developing country. I am focusing on Thailand but have a bit of connection in Peru that I believe I can get the ball rolling if I have backer. Thailand because I am a Thai and believe that the family connection could pull it off. Thailand is a top destination for medical tourist so there is not problem there. I also plan my business plan around social issues as well ... I even make plan what I want to do if I happen to one day participate in top political position. One will have to hear me out since it would be too long to type. I hate to use the world social engineer but prefer to use the word "changing current social direction" . I think people need to get back to basic and slow things down. What is the point of living if you don't have time to relax and enjoy. My program will involve young people in Thailand to have a hand in taking care of retirees, both domestic and from other countries. They will get language and culture skills including being down to earth as human interaction and learn the wisdom from the oldies. Another group of what I want to do involve each Thai national to get free paid vacation in Thailand. There are many places that are currently owned by the government at beaches, mountains etc. These places can be developed ... using prisoners or others to create jobs in this tough time while interest rate is low. ... I have it all planned out as i believe that each countryman needs to enjoy what the country has to give. Rich or poor should have a common award from being the citizen.
Two days ago, Burma and Thailand signed a deal (for the second time as after the first time there was a political stuff took place) to create deep sea port in Burma and railroad to the east coast of the Gulf of Thailand. This is an amazing project in itself. Why? Now ships just unload cargo containers in Burma from the Indian Ocean and get on the railroad to Thailand.... unload it and get on their way to China sea. Ships will no longer go through the channel in Singapore and Malaysia. This will save them tons of gas and about 5 days. Of course, Singapore and Malaysia won't like it and are pumping up so much money to the opposition camp to his idea. Finally after the long long long delay, it resumes again.
Anyway, so much I want to do just need backers. This is just not money but for the progress of humanity ... making lives better.
I even thought of a system where TIME is the rewards giving that compensation are the same across the board. This will be done through government own businesses or government positions. The more important the job, higher skill, higher dangerous work = less time on the job. No body will have to worry about money as it will be paid to the comfort level. If you want to work more, you can do it but can't double your work in government sector OR better yet you invent things, start business etc.
I also have an idea that if you are a public trading company, the highest salary can't be more than 15X of the avg lowest 10% of the worker in the company. This will create a lot of out sourcing on lower job positions to other companies = create more business opportunities and grew small businesses.
Ok, I better stop right now before I type a book here.
