I'm not sure why it's unfair for first-time founders. STEM founders are largely better off not innovating and instead helping FB sell ads. Tax incentivizes like QSBS for companies, especially bootstrapped co's, help. Job creation & technology invention is why the gov already has direct programs to give tax money directly to startups (SBIR, R&D tax credit, ...), and this is an extension of that encouragement. We need more, not less -- otherwise it'll push even more to the concentration of VC-funded fintech startups and FAANG.
I would agree that QSBS support for the already-rich can be less effective -- your case of angels. I'd rather see improvements on the capping structure, vs pushing incentives even more (15-30%!) to working for FAANGs.
