Stille wateren hebben diepe gronden
Achter de relatief stabiele inkomensongelijkheid in Nederland gaan grote veranderingen schuil. De inkomensongelijkheid is de afgelopen veertig jaar wel toegenomen maar viel vooral minder sterk uit doordat vrouwen in lagere inkomensgroepen meer zijn gaan werken. Ondertussen is het inkomen van mannen…
