This is something they do, Marvel rely on outsourcing and using ununionised labour [1], and it shows in the recent films and TV shows they've made. There's a drop in the quality of the VFX. Wages for VFX artists aren't too high, as I've said, they are some of the most underpaid workers in the industry, and their protest against this is always stomped out. For a VFX worker it must be highly frustrating working in an industry where other workers are unionised, but they aren't.
Can you point me to a clip on YouTube that you would consider to be good Bollywood VFX? I've mostly been exposed to the most comically bad Bollywood VFX.
VFX artists can definitely make a good living. Their salaries are comparable to tech if you remove the stock portion. They also work crazy OT and are paid hourly which means big money. That's true if you're more senior of course.
