Gladness: "I'm glad i don't have a million dollars to manage in my bank account, just getting the best from my small savings is stressing me out!" 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.
