While there's obviously a lot of nuance past the basic class definition. I do think that it's an incredibly useful starting point for any analysis. Looking at whether a person's primary source of income comes from their labour or from capital they own helps understand where their interests lie. I completely agree that one should not use reductive analysis here, but it's a good starting point, and it's the basis for class contradictions within the capitalist society.

Absolutely, it's class analysis 101. Not wrong per se, just not the whole picture. But a good starting point.
