Yes, I agree with the view that the traditional handicraft industries were ruined under British rule. There are several reasons to support this view, which are discussed in detail below.

Lack of government support
During the British rule, the government did not provide any support to the traditional handicraft industries. They were not given any subsidies, loans, or tax exemptions. This lack of government support made it difficult for them to compete with the imported products that flooded the Indian market.

High taxes
The British imposed high taxes on the Indian handicrafts, which made them expensive and unaffordable for the common people. On the other hand, they imposed low taxes on the imported products, making them cheaper and more accessible. This unfair taxation policy led to the decline of the traditional handicraft industries.

Introduction of machines
The British introduced modern machines for mass production, which made the production of goods faster and cheaper. This led to the decline of the traditional handicraft industries, as they could not compete with the mass-produced goods. The British also discouraged the use of traditional methods of production, which further contributed to the decline of the handicraft industries.

Exploitation of artisans
The British exploited the artisans who worked in the traditional handicraft industries. They paid them low wages and forced them to work in poor conditions. This led to a decline in the quality of the goods produced, as the artisans were not motivated to produce high-quality goods.

Conclusion
In conclusion, the traditional handicraft industries were ruined under British rule due to the lack of government support, high taxes, introduction of machines, and exploitation of artisans. These factors led to the decline of the handicraft industries, which had a negative impact on the Indian economy and culture.
