Unemployment also means that people who actually want to work (and who are unemployed) cannot work with what they are qualified for.
Unemployment is a social problem, and low unemployment and high employment are important in order to develop and maintain a welfare society. For each individual, work is the most important insurance for their own welfare and social inclusion.
If the aforementioned law were approved, and the unemployed began to look for work imminently (even leaving aside some pretensions), many of them would get a job in a shorter time than if this law were not approved, which would decrease the country's unemployment rate.
