(Im talk about a system for Switzerland)
I propose a "basic income" no strings attached (Everybody gets X$ per month and all wages are reduced by X$ is the short version of how it works) with this we replace all the diffrent social systems we have nowdays (money for kids, unemployment, AHV (money for the retired ...).
This will liberate people in the sence that they don't have to hang on to there jobs even if they are badly treated, they wont be social outcasts if they dont have a job.
instead give them insentives to improve there education (and thereby you could then get a job in a high tec economy), to be more entrepreneurial (find out what people really need and trie to provid it).
A more importend example for the people here is app marked development. App marked made it possible to start a project in a small team and make money relativly fast. The insentive to trie something like this is much greater and you can't fall that far.
It may not be the best model in pure economic groth terms but I hope it is a good model for a sustainable healthy society in a world where it is very hard to have full employment (because the economy changes to fast).
