Ageing os a country

I wan't to underline one thing.

See This, where South Korea is making transition from country ageing and losing percentage of agricultural workers. This is only road to high income country. Every high-income country, beside Kuwait, Brunei and United Emirates has median age over 30 and every of these has less than 10% workers in agriculture. countries like Greece or Portugal face real problem, because they have to change their workforce structure or they be left behind. Countries like Czech or Slovak Republic should reach as high income per person as UK or Canada. Countries like Vietnam or Bangladesh could recreate slide in South Korea style.
