That's a pretty vague ask. What level of detail are you looking for? Whose economy? How much aggregation and cleaning are you willing to do yourself? If you're in the US, government census microdata might be a useful place to start. Or Bureau of Labor statistics.

I'd question the accuracy of that aphorism, though, given that the bourgeois have what's generally acknowledged to be a misshapen and simplistic view of the economy, which is one of the reasons it keeps slamming into a tree at 70 mph once a decade.
