One of the primary culprits of allergy-inducing pollen is ragweed and a healthy and ecologically stable meadow generally won't harbor ragweed because ragweed likes to grow on disturbed land. It's also worth mentioning that the effect of ragweed is often conflated with the goldenrod because they flower at the same time later in the summer and early fall.
That said, it would be interesting to try identify when your allergies flare up and what plant species are flowering at those times. The airborne pollen that causes allergies rarely originates from meadow plants because most of them (goldenrod included) rely on bees and other pollinators as a means to transport pollen from one flower to the next, not the wind. This means meadow plant's pollen is often too heavy to be transported any distance in the air.
