From an ECONOMIC stand-point: can marriage equality and civil unions being more prevalent help boost the economy?

I feel the more people CAN legally bond as a couple- they will not only spend on any number of businesses involved with cermonies, they will also settle in more tolerant areas and add to the overall economic prosperity. Rather than moving away elsewhere. Basically, tolerance literally equals growth.

(please, if you have something against non-straights- this is not an invite to express any personal negativity.) Thanks.
