Why would black ever accept the Queen's Gambit?


Playing as black - why would one ever accept the Queen's Gambit? Looking at games and main line openings it seems like a struggle at best. There are things black can donand there are things that might work. But in the end wouldn't it be better/easier to just decline? Is there a strategy for black for the QGA that I'm missing? Thanks

Why not? It's just a move. To me, half the Queen's Gambit Declined positions look more of a passive struggle.
One major benefit is that the white player probably sees it less often and you can get used to the positions.
Dont see anymore struggle in QGA then in QGD. And looking at statistic in https://www.365chess.com/opening.php?m=4&n=23&ms=d4.d5.c4&ns=7.8.23
B is doing a bit betterby accepting. Though all three major choices are just fine and about equal chances.
This is not really true - at the GM level black is struggling a lot more in the Queen's Gambit Accepted than the Queen's Gambit Declined. However below GM level it might be a different matter

The QGA is a "hypermodern" approach in that it cedes White some central control in return for an exceedingly solid pawn structure. Note that all of Black's pawns are close to home and thus hard to attack. Contrast with the Carlsbad, where the minority attack is a problem, and the Tarrasch, where the IQP is a problem.
The problem with an approach like this is that giving up squares like e4 and c4 without a fight can leave your pieces short on squares. However, players with the Black pieces have found ways to deal with this potential issue, so they will let players with White struggle against the most statically sound setup possible.

Because its one move. And unless you're one of those good players, its not really going to matter whether you take the pawn or not.

At chess.com's Opening Explorer, there's not much difference in the master games' results for Queen's Gambit Accepted, Declined, and the now most-popular Slav Defense.
At below master levels, I like the Slav and have done very well with it, perhaps because it makes it easier to get my QB into action.
