Keep your country secret. That is my advice.
Americans are brusque, opinionated blowhards. Especially the aging baby boomers who are looking for places to retire. They don't know a whole lot about the Philippines. If they knew, they might come here. They would likely gripe about some aspects of the culture , as it is so different from what they are used to. You don't have to put up with that. Simply don't tell them how cool it is here. Tell them about the horrors of cramming into a Jeepney full of chickens, but don't tell them of a romantic ride with their sweetie on a tricycle to the beach, of scenery so gorgeous a photograph can't do it justice, of the tax breaks they can get by leaving state income behind, and the social security income they can acquire by being old and having American- citizen kids in the Philippines. Don't tell them that they can build a palace for $100,000, and have a housekeeper and a gardener and a cook and a bodyguard and a driver, all for less than $400 a month.
Tell them "we like sitting drunk under the mango tree watching the buses fly by. We are fine with that goal for our lives. We are proud of our achievements."
Multi-culturalism is offensive. Outside money is tainted with foreign cooties. Tell them "We like it pure, we like it simple. We don't aspire to be like you because we know money can't buy happiness."
