Sweden spend 70.1% at work and 29.9% at leisure (non-productive). In the United Kingdom these are 84.5% and 15.5% respectively. Sweden has the highest total tax revenue as percentage of GDP of any other ranked country. It is also the only country in the world with a total tax revenue higher than 50 % of GDP.
If the working week were to lose 8 hours (one day) then people would earn less as there productivity time has reduced, thus with less income their buying power (and saving power) is also reduced. When salaries are reduced, then so are the treasury coffers and state services.
Socialist France introduced a 35 hour working week. The 35-hour week came into effect in 1997, as the Socialists' big idea for reducing unemployment. Unemployment fell until 2000, while the economy boomed, but then rose again, to just under 10 per cent. In recent years, the introduction of this was seen as a disaster which had lumbered the state with �10 billion a year in additional social charges and that it had demoralised millions of workers as many wanted to work an extra day and thus earn more.
Employers despised the plan, as they were forced to keep salaries at the same level while getting less work from their employees. But employees, enjoyed the extra time off allowed by their shorter working week. Working mothers were especially pleased, as it allowed them to see their children.
But with France's economy sputtering, smaller businesses in particular struggled. And the system was attacked as yet another regulatory burden on those wanting to pull themselves up the economic ladder. Hospitals and other essential services complained that the 35-hour week had left them with severe staff shortages.
