@jeffowski well... Writing my doctorate, I bought articles for about 2.000€ (and wrote them off via tax refund down the road later) and that's just.

But I agree: I was indeed privileged to have 2.000€ to spend and via that tax-reclaim, indeed the public paid for this little part of my doctorate, and I paid it back through good medical service and determination.

But everyone seeking knowledge and enlightenment should always have free access to science.

Professionals should have to pay.
