The women's game has grown massively in the last few years and with it, the quality is improving. I do admit, the goalkeeping has always been the weakest aspect of the game, but you can't knock some of the outfield play. Over time, this will only improve further but it has to be given the chance to grow, rather than have men just moan women should get back in the kitchen (i have to hope these men don't have daughters)
Will it ever be on par with the men's game? Most likely not, but Serena Williams would get likely beaten by a man barely in the top 100 rankings. That doesn't mean Serena is not still great to watch or that she is inferior to her male counterparts.
In regards to pay, of course they don't bring in the revenue to earn anywhere near to the men, but in defence of the USA women's team, they do actually win World Cup's and the Olympic's so are a lot more successful than the men. The women's game is actually bigger than the men's over there so i can understand why they complain about that based on both points.
While people knock the quality of football played, at least you are watching people play for the love of the game rather than the money. The lack of diving and rolling around like they've been shot if they get tackled is also refreshing.
