The premise of my post was a change to an auction-style H1B program.
Let's assume there is a $FooCorp in Alabama looking for a SysAdmin but not having much luck. They'd like to spend $70k and enter the H1B lottery under our current system. Maybe they win, maybe they lose but can hire an H1B for $80k from $OutsourcingFirm. Under an auction system, let's examine what happens instead.
$Hooli (and other SV companies) are offering $135k for SDEs. Because $135k > $70k no H1Bs can be imported as SysAdmins for $70k. This raises the cost of SysAdmin work across the country for employers. The new baseline is now somewhere above $70k which is the price it takes to attract citizens (or otherwise eligible residents) to $FooCorp.
Under an auction system, $FooCorp still needs a SysAdmin and they have 3 options:
(1) do without a SysAdmin
(2) pay more than $70K to attract an already eligible to work SysAdmin to Alabama
(3) pay more for a SysAdmin than SV pays SDEs in order to hire an H1B
Let's look at those options. If they need a SysAdmin, the first option isn't really feasible. If the role is optional, this might be a situation where they decide to do without. That means there are two options left, and the rational decision depends on what the true market value of a SysAdmin currently is. If $FooCorp can pay a citizen $100k to move to Alabama, there isn't a skills shortage. If $FooCorp can't find anyone to move to Alabama to be a SysAdmin for less than $135k, there might be a legitimate skills shortage and then the H1B program is attractive again.
It's worth noting that if $FooCorp can't find a SysAdmin for less than a SDE to move to Alabama, the true value of a SysAdmin is at least $135k (in this example). Under the current system, SysAdmins are being short-changed, both H1Bs and other eligible SysAdmins in our workforce.
There is no such thing as a skills shortage. There are only greedy employers looking to abuse a system to underpay all workers, whether they are H1Bs or otherwise authorized to work. Anyone who tells you there is a skills shortage is making money off telling you that. Don't be a sucker.
