What a bitter person you are...
OP is clearly contributing to the local economy in some way. He brings his money from abroad and spends it here on accommodations, food, transportation and other activities. Every foreigner coming here without working in Thailand is doing the same. I don't see business owners complaining about them.
And clearly, he can afford a visa as he offered to pay them extra, they just won't give it to him.
Any foreigners here are given visas because they contribute to the country somehow. Retired people are allowed to stay long term as they don't work here and show they have money from abroad that can support them throughout. Married foreigners support their Thai wife (and family if they make one). Work permit holders share knowledge from their expertise and contribute to Thailand's economic development. Tourists are given visas to spend their money on holidays here. The list goes on and on..
OP, wish you luck and since immigration will not honor a visa that you are entitled to get at the moment, I agree with other posters that using an agent may be your best call.
