Probation periods or punishment periods?

Having changed jobs I'm currently in a probation period. I have, for a time, lost many of the advantages of full time employment I previously had, and it feels like a punishment for exiting my last employment. Recent family events have made me think quite hard about things like fitness, healthcare and pensions, none of which I'm entitled to during my 6 month probationary period.

I can, grudgingly, understand that the notice period is short during this period but withholding employee benefits feels like mixture of punishment and old fashioned 'you should be grateful for a job' thinking. When you're trying to hire clever, in-demand individuals who want to work in autonomous teams where their contribution and commitment is valued, you need to reflect those qualities in how the company treats its those new employees day one.

And as my friend Ian pointed out, it actually shows you're not confident enough in your hiring procedure to trust that you've made a good hiring decision. That makes me nervous about the company. Have you hired badly in the past and don't think you've fixed that yet? So actually, who should be sitting on the naughty step?
