Cost of basic dietary needs in Amsterdam

Hi,
I was checking the prices for meat in Amsterdam and I can not understand the pricing.
It seems that the cost of beef from supermarket or butcher is ~30 euros/kg.
While the cost of chicken breast is ~6 euro/kg.
This essentially makes beef 3x more expensive than I buy it here in Greece while chicken is cheaper.
Why is beef so expensive? Is it the same also for fish and pork?

hmmmm maybe thats steak because its not my experience of it.
