It is a one-time fee, not a recurring one, that applies to new applicants. Indians will use all their savings to pay those extra fee,s and companies need Indian talents.
But, in most cases it is the company that needs to pay the fee not the employee so if it went from 2K to 100K, I don't know how many companies will be okay with that. And not everyone going to US is not just to Google or Microsoft, there are also small companies that are working with 100 - 200 employees who will never able to afford that 100K fee so they won't hire anyone new until there is some kind of revision or exemption.
And this is not just about h1b or tariff, it is US showing their hate against India and for that reasons we may not be welcomed in there as before.
