Tech has a higher profit margin, but is a smaller industry. So depends which metric you want to use to define better- Efficiency or total profit. Comparatively the largest pure tech (none hardware) company Google is valued at $290bn publicly, and the Financial Times estimates the largest pure oil company Saudi Aramco privately at $2000-$7000bn based on the size of it's reserves.

It's a fruitless argument either way. I simply meant the fact industries with larger figures exist, doesn't mean VCs just look at the random top-line numbers and ignore an industry because it's 'not big enough' when you're dealing with billions of dollars.
