There would be endless queues if those Bulgarian devs would get even a fraction of that rate. They were lucky if they were getting more than $10-15/h. I also doubt there would be huge shortage of US devs willing to do the work if they were to get $120-150/h. The other problem is modus operandi of a standard software agency- it just suck your sole out for those extra lines of code.

The developers don’t get all the money they’re billed out for. The billable rate goes to the company to pay business expenses, of which developer salary is a minor fraction.

I think that's pretty much what I wrote in my comment. Agencies bill through the roof yet the devs get pennies.
