"By allowing MNC's into the country, the people are subject to being used as labor for the factories, decreasing the income levels"
WHERE IS YOUR PROOF!!!
There are a myriad of examples out there, one of the most relevant being China, From the 32nd in 1978 to the 3rd largest exporting country in the world in 2004,
China’s export boom was accompanied by substantial inflows of foreign direct
investment in the same period. Exports by foreign-invested enterprises in
2004 were $339 billion, comprising 57% of China’s total exports.
FdI improves the balance of trade for developing countries, as it allows the MNCs to produce using the resources from developing countries, and internationally trade their produced goods with other countries, increasing exports in developing countries, and improving their balance of trade.
