It's not any particular feature - it's the licensing and royalties paid on tech patented and owned by other parties in the US, or by parties the US recognizes. Since that's not reciprocal, it's a drag on any US company, or company that respects US jurisdiction.
Put enough sticky notes on a Tour De France rider and you'll eventually guarantee their loss. That's the one-sided policy problem with the US, internally. Now if other riders are doping and using secret electric motors, but the stickied up rider can't cheat in the same way, then you just guarantee their loss, even if it's only a little degrading.
We need a better, more accountable, and more transparent international trade framework. Something that shuts out bad faith players that use slave labor, child labor, exploitative wages, things like that, and appropriately scales tariffs and other mechanisms to penalize the violations appropriately.
I'd much rather the playing field be entirely fair and even than do the current US thing of "well, we're going to impose a lot of moralistic and patronizing rules on ourselves, but allow anyone anywhere else to ignore those rules, because it makes for good political theater back home, and it makes shareholders happy."
> The Space Exposed Experiment Developed for Students (SEEDS) allowed students the opportunity to grow control and experimental tomato seeds that had been exposed on LDEF comparing and reporting the results. 12.5 million seeds were flown, and students from elementary to graduate school returned 8000 reports to NASA. The L.A. Times misreported that a DNA mutation from space exposure could yield a poisonous fruit. Whilst incorrect, the report served to raise awareness of the experiment and generate discussion.[17] Space seeds germinated sooner and grew faster than the control seeds. They were also more porous than terrestrial seeds.
