What is God's name is going on with the Ethereum Mist Wallet node sync?

I mean seriously???

Stuck on block 4,219,024 and the Chain Structure is 669800+ out of 695000+ going backwards and forwards.

So so aggravating!!! Coming from Bitcoin.

How is the public supposed to sit through this kind of sync?

10GB's x of data, hours and hours of downloading, no indication it is every going to end.

I was looking into developing for Ethereum, but after this (ridiculous) the bloat is intolerable.

If ETH nodes cannot sync, this crypto is not worth $375.00.

Sync is out of control.... now Chain Structure is 826000 out of 850000 what on earth is this?
