so why do men say shelo osani isha??? i mean men are thanking G-D that they are NOT women
Bemakom shebaalei teshuva omdim, afilu tzadikim gemurim lo masigim.
We are by design imperfect creatures. We're put on this world to perfect ourselves. The level that one comes to through work surpasses that which comes naturally.
Each mitzvah is an opportunity to improve ourselves and fulfill our mission on this world. Women may start off higher; but because of that, they have less they need to do to grow.
We relish each additional mitzvah, the same way we pray for long life, as additional opportunities which can bring us higher than had we never had the need for it in the first place.
Tzaddikim are on a higher plane than malachim, even though malachim are sin free; because tzadikim attained their level through their own work, and sanctified G-d's Name in the process.
This world is designed as a place of work to bring ourselves close to Hashem. We make the brachos in the morning appreciating those opportunities. This doesn't imply that men are superior to women; it implies that it is superior to be a man than to be a woman; as far as growth opportunity goes. Sure, it entails more work; but to work is why we're here.
