You and I seem to have different ideas of an employment social contract (or non-existence of one). Unless you're interested to dig into that difference, I don't think we have anywhere else to go with this thread.
Thankfully: "My bank account (thankfully) lacks a Bill Gates' sized stash of greenbacks, it does mean that it's impossible to buy a mansion though"
I'm not criticising the concept of a million dollars in either of these statements. Thankfully, as used in the original context means something quite different to the meaning you've derived.
I might still actually have a bone fide criticism of a million dollars, but that's neither here nor there in the context of either statement.
I think wrapping it up's a fair shout though so no hard feelings and all the best.
