Does this have the same sarcastic feel in German as it does in English? I guess it probably depends on how it is said. In English 'thanks a lot' is pretty much always sarcastic, is there anything that is the same in German?
"Pretty much always" may be a 'slight' overstatement.
"Danke Deutschland, meine Seele brennt!" There's also a song :)
Why isn't "ich" necessary here?
You wouldn't say "I thank you" in English either.
