In Ireland PhD stipends are closer to 13-17k. It's not a perfect comparison because the PhD stipends are tax free, so your comparative salary would be in the 17-20k mark. That said, Postdoc research positions are much closer to 40k than 30k.
That's still pretty miserable. In Germany, an assistent professor or postdoc makes 60k Euro after a few years, even when they are in the pay scale that only requires a master's degree (TVL-13).
