This may be true if your working with two assumptions. One society is a meritocracy, which isnt true in most cases success is determined by birth and luck rather than merit, other comments have mentioned this so I won’t get too deep into it.
The other is that politics and government are just about getting the smartest most credentialed people in the room and then they will solve all the issues. While we do want smart capable people in office this view ignores the other qualification a representative needs, to identify with and understand the people they’re representing. If Congress is just a bunch of lawyers from Harvard they don’t understand what it’s like to be a single mom working on minimum wage and are unlikely to increase that wage. If there only talking to people in the successful upper middle class that they inhabit they’re less likely to see the struggles of the common worker. This is why we need working class representatives to give a voice to those struggles.
You make a good point. In my experience, American society is a meritocracy - my family started out with almost nothing and now we’re upper-middle-class. I know plenty of other people with a similar experience; this experience is one reason why so many immigrants want to come to the USA. However, it’s clear that my experience isn’t universal. I don’t identify with the many people here who don’t think we’re living in a meritocracy, and I don’t identify with people in generational poverty despite having experienced poverty myself. I admit I don’t understand the former group (are we living in the same country?) and my understanding of the latter group is only academic. I can see why people in these groups wouldn’t want a representative with a life experience like mine.
On the meritocracy argument if you think of it like economic success = merit = hard work and determination, I think that’s wrong because there are two things required, that are matters of luck, to turn that hard work into economic success.
One you have to be talented, or have some innate ability that others may not have. Just like some people will never be a top basketball player no matter how hard they work because they just don’t have the body for it many people just dont have the brain to understand medicine or law or business at high levels. There’s nothing wrong with not being able to do that though and people shouldn’t be punished by having a lower standard of living because of it. Hard work !=merit
The second is you have to be talented in a field that the market values. The classic example of this is the starving artist but even if you’re talented at child care you may not be payed well unless you “advance” to becoming a manager which you may not be good at. This also goes into how we value work as a society since that childcare worker is doing more good for society then a Google engineer figuring out ways to click ads, but the latter is payed far more and is deemed worthy of merit. Merit != Economic success
If you’d like to know more about this perspective I’d recommend reading “the tyranny of merit” by Michael sandel. It’s written by a Harvard philosophy professor on the reality and the moral and political implications of the “meritocracy” as it exists in the U.S. today.
