The conditions look like the only requirement is being a professional with college degree.
I am an immigrant (not to US though), so looking from this standpoint. If I wanted to move to the US, H1B would be a pretty straightforward way for me to do so - as it is for many professionals now. With this path cut off - what is left to people who are just good professionals in their field, but maybe not exactly Nobel laureates? There is Green card lottery, but being a lottery, it's not ideal for life planning, and it doesn't account for one's professional achievements.
Do you think US companies decide whom to hire for no reason? Not being available for interviews locally, not speaking English natively and needing a visa sponsorship already puts you at disadvantage compared to the local talent. If they still decide to go for you, there sure is a reason.
The reason is often money. Even with visa sponsorship. Perhaps $100k is too much, but ~$5k is too little.
The $100k fee basically makes it not about money. It's going to be more expensive to hire a foreign worker - meaning that if they're chosen over a domestic applicant, it's for a real reason, not just because they'll take a lower salary.
