Taxes in India were significantly increased by Britain during the war, almost tripling if memory serves. India was still quite impoverished at this time, so it's no exaggeration to say that this imposition represented a massive extraction of wealth from India.

It's not too long (15 minutes), but it's a very good speech about the economic situation in India before and after British colonization.

as an Indian, I have heard people around me say, britishers looted all of our riches, the riches being gold from the western, central, southern kingdoms in both late 18th century and throughout 19th century; we had high taxes imposed and east india company had trade monopoly, then in 20th century the taxation was getting out of hand and a lot of indians were becoming slaves at indigo plantations, then slowly came the revolution and in mid 20th century wwII, some indians got control of our iron and coal mines, tata's and birla and I forgot, our mills and by now we had some educated-literate folks which led the revolution...

if you go on Instagram for a while and scroll, you'd eventually find some content with indians in the comment section blowing up about our past glory and ancient hinduism and what not. We lowkey still have tons of uneducated idiots
