What would happen if everyone in Sweden would get a job?

The law of supply and demand applies to workers as well as goods. With high unemployment workers compete with each other for jobs driving wages lower; with low unemployment employers have to compete with each other for employees driving wages higher. Economists see employment and inflation as correlated. Periods with low unemployment generally have high inflation due to higher wages causing the price of goods to go up as well. The inverse is not always true. In the 1970’s the US experienced “stagflation” where we experienced both high inflation and high unemployment.

True, but since Sweden is a member of the European Union, and people from EU-states can go to work in other EU-states without needing a visum, unemployment rates would have to go down all over the EU first. And even when everyone in the EU has a job, companies would probably still try to get immigration from non-EU countries via green cards before significantly rising the wages.

would it be good or bad for sweden if this happens?

It’s good for any country the day everyone in it finds a job.
