Please read the thread carefully. How on earth your mind can jump from public sector pensions are contributed to by public funds all the way to suggesting that public sector employees (of which I am one) should work for free, I have no idea.
You really aren't a very smart person
Your public sector pension also has contributions made by your employer, the public sector, your portion of payments in is probably less than half of what goes into your public sector pension contributions.
General taxation is public funds.
