Are we saying software engineers making $125-150k are middle class? If so, then yes this I absolutely believe this is true. These will still be high level people for the most part that will up our game in my opinion. Thats in the opinion column, hard to prove. But this fee may have a net negative impact on jobs for Americans as it will push more companies to simply outsource to these countries rather than pay more in the US. So you need to tax that too. And then they will find some way around that and we will need to tax that new thing. I don’t like this game, it is trying to stop progress in my opinion. But I guess it is a balancing act and who knows where you set the line. Adding friction to it will definitely make it so only higher quality talent migrates here, that much seems clear.

>$125-150k are middle class?

I would think healthily so, even if on the upper bands [0]. I personally see "middle class" solidly as $50k-150k household income (2 adults 1 kid)... but I live in the South. Two decades ago I lived in the bay area for less than $100k (electrician)... and that was regionally closer to the lower end of "middle class," even out in Hayward.
