The first policy I would recommend for the country is to encourage full employment. This should allow the discouragement of unemployment, as this can help to ensure sustainability. They can increased retirement age or do away with so as to ensure continuity with employment. The other policy will be to increase the incentives for those who care for the elderly as this can be of help too.
Birth control, laws to enforce looking for employment with proof and increase retirement age to 62. I personally think no one should have to work after age 62 if they have worked full time after age 18 or at least attended college and then worked full time up to age 62. Hard working people deserve R and R. That's the goal after busting your hump most of your life.
Why would you recommend BIRTH CONTROL to a country with LOW BIRTH RATES????? That's just stupid! We're trying to suggest to them something that would HELP them with the fact that they have a LOW BIRTH RATE, birth control would still keep this ISSUE!
