You're not actually wrong. Reversing it would have immediate and far-reaching benefits for large companies. I suspect many of those would respond by going on hiring sprees.

And also, reversing it would encourage more people to start software businesses. So while not a tax cut for small businesses that don't exist yet, it does help those future potential leaders make the leap.

Backwards. Startups are typically quite cash poor at the beginning. This gives a huge advantage to the already established, rich companies.
