parents paradise --kids are cheap by rail

This country is designed to be the parents paradise. Generous parental leave, subsidized and highly affordable child care and incredible tolerance and respect for children as a part of the daily life. But I think the railway company has gone overboard. Kids get seats for quite nearly nothing. While it's literal, it should be. 2 Children can accompany a paying adult complete with a reserved seat for.....20 kronor --round trip --IN TOTAL--anywhere.

I just bought tickets Stockholm-Malmö for two adults and three kids. One of the minis is the 5-month old daughter. She gets her own seat. The total price is 2480 for FIVE seats. For two adults alone I think that's a pretty hefty fare (mind you it's a reduced saver's fare.) Full price in 2nd class would be that much for one adult.

Now I'm not complaining as I'm now on the receiving end. But the former non-parent in me says "That's not really fair" for the childless or childfree when traveling. Reduction in price? Yes please. Virtually free? --why?
