I started researching this issue when I became good friends with a Korean family who moved in to the house across the road. They moved to NZ because they said that Korea was stressful, corrupt to the core and the last place on earth they would want their children to grow up in.
My honest advice is to have nothing whatsoever to do with Korea because it a worse version of Singapore plus it is on steroids which is cheating.
But you are praising SG sky high and at the same time saying Korea is SG on steroids?
In any case for SG, what would normally be considered disgusting or abhorrent practices in other countries have been rendered legal through acts of Parliament.
