I have been gone from Boeing for less than 5 years. Not long in the grand design, but long enough to compare.
The corporate world su-ks. The type of people who make it to management in all companies su-k.
All things being the same, I'd rather work for a company that su-ks with great benefits than a company that su-ks with less than stellar benefits.
I'm going to be ripped for this, but yes, I'd go back to Boeing. Its sh---y but the 10% match in the 401k will get me out earlier and the cost of insurance is the lowest I have ever found.
I'm not going to be happy at work anywhere, so I might as well have my pockets full.
