SaaS price drop?

Will competition from developing countries reduce SaaS pricing?
What prevents them from charging say, 4x or 10x less?

I have seen some aggressive trends with startups precisely charging 10x less than traditional companies, but hopefully it's only at the smartphone-app level for now.

Will this trend grow mainstream?
It's quite strange that the biggest money in engineering for developed countries lies precisely in a field where everyone can play.

PS. I ask because I'm considering to take a break from my STEM career to make a startup :)
