Because of this, we see individual stars, and we see a yellowish sun and a blue sky, not a brilliant white sky with no discernable solar disk, or stars. Also the scattering is something like proportional to f^4, very frequency dependent. Which is why the sky is blue and the sun is reddish at sunset and lunar eclipses are reddish.
