That's exactly right. The rating shows your relative strength against the average strength of the rating pool. The chess.com blitz pool is about 250 points stronger than the uscf standard pool. This shouldn't surprise people, since chess.com is international, and incorporates a large number of people who play blitz on a daily basis. We should expect USCF standard players to experience a rating drop here. I just find it strange people talk about the ratings being inflated -- they aren't.
Actually, you can't even tell THAT from the ratings. Chess.com could inflate or deflate all ratings by 500 tomorrow, but that wouldn't indicate any particular strength or weakness of players from particular countries. It would just mean the scale is different.
Seriously? You haven't played in a USCF tournament in -over- a year. Its been 18 months. Why don't you get an -active- USCF rating before you start talking? My comparisons used people who play regularly in both USCF and chess.com events. You wouldn't qualify since you don't play enough to have a reliable rating. Seriously, people, work on your thinking before you post.
With a blitz rating of 1575, its not going to be hard for you to get a USCF standard rating of at least 1775. Just go try, you'll be pleasantly surprised.
