Ok question: Are the taxes cheaper in thailand if you give up your us citizenship?

In April I purchased the 5-year elite visa but I have a great idea for a brick-and-mortar business I would like to explore. What would be required for me to create this business in say, Khon Kaen? Would I have to find a Thai business partner, and would they have to own 51% of the business? Would I have to employ 4 Thais for every farang (and does that include myself)? What licenses would I have to get (it's a type of animal café/restaurant)? I heard I can also apply for a business visa which can combine with the elite visa. Is that true? Would I be able to get a business visa (instead of the elite visa) which could be renewed indefinitely if it is successful? Thanks!
