What this system boils down to is a compulsory savings scheme. So an alternative would be a voluntary savings scheme, which would have higher efficiency by not consuming resources for administration.

What Swiss specifically have - we all pay social deductions, within 3 pillars. If you end up unemployed, then you are entitled to 1-2 years of unemployment benefits in 70% of your former income, with some reasonable cap. That is if you worked 100%, in perm contract, at least a year in a row. Otherwise not entitled or payments are much lower.
You have to actively search daily for new job and prove it to your unemployment councilor, otherwise they will cut benefits. Those benefits are really structured in a way to pay you while you are looking for a job, not to have some extra long holidays on everybody's else budget.
Motivating setup, and since there is a social net of that 70% of my income, I am not frightened on the prospect of losing job and needing to store enough cash to live at least X months/years without any income. Handy when one has big fresh loan on his shoulders.
In Norway you can get 1-2 years benefits at about 60% your previous annual income with a cap near median national income.
