In a welfare state, the government of this state assigns a huge amount of allocation from GDP for the social security purpose. Most of the funds go for the unemployment allowance. And obviously, this huge amount of money comes from taxation. So, unemployment provokes government to increase tax rate.

If the level of unemployment is reduced, the government will not spend more for the unemployed people, rather it will spend these funds for the development activities of the country.
