I mean, yes. A country that maintains unnecessary employment in agriculture won't have the labor force to develop industry.

Accumulated capital, will by necessity flow towards other countries, where factories can be built and staffed. Meanwhile, because of the lack of potential competition with industry, the agricultural workers will be treated as poorly as the capital owner pleases. But that doesn't mean they'll be happy to be expelled from their lots of land, even if it'll help them.

None of that should be a mystery.
