Thais are not famous for their mathematical skills and the government is no exception. Just let me make a simple picture: there are around 3 million foreigners living in Thailand. Trying to find an average monthly spending between retirees and high income corporate earners, I settle after some counting and reading on 60,000 thb per month or 720,000 thb per year. That means that foreigners living in Thailand inject 2.16 TRILLION baht into the local economy every year.
As a government I would pamper sych a chickennwith golden eggs...
