Poland needs less people and better use of its resources. There isn't exactly a labor shortage at the moment...
What Poland needs is better use of its resources
. Not more people. A rapid increase in population would increase the unemployment rate.
Poland also needs a stronger economic growth to get tax-money to welfare
. Many hospitals (including "mine") have extremely big economic problems
now.More small companies
and increase their incitement to hire 1 more person
. If every small company would hire only 1 more person, the tax-money that can be used for welfare would be taken to a whole new level
. And the expensive unemployment would decrease a lot.
However, in a longer time perspective, more young people are needed to manage the pensions. This is one of the biggest economical problem in many Western countries. Too many old people, and too few young ones. An economists nightmare.
