Actually the problem these days is that standard-essential patents are considered less valuable because they tend to require FRAND licensing. This is the problem companies like Motorola and Samsung ran into during the smartphone patent wars. They could not ask for injunctions or high royalties for many of their patents as they were standards-essential, and they lost a lot of leverage.

Secondly, standards setting bodies are usually a conglomerate of members from competing companies and hence a huge political bureaucratic mess, so it's not as easy to get something into the standard just for some money.
