Ferrari's pledge of loyalty is somewhat shameless, because he is destined to become a politician, while Lynch is still just a merchant.
Politicians pledging loyalty to merchants may seem unreasonable, but this is precisely the norm in the Federation right now; capitalists are capturing one politician after another with money and interests.
You can't blame politicians for shamelessly working for capitalists, because from the start, small figures like Ferrari have established a solid relationship with the capitalists.
Lynch provided him with the necessary campaign funds, allowing his campaign posters to plaster every corner of Sabin City, enabling him to frequently appear on television, and even making his campaign vehicle longer than anyone else's and his gifts better than everyone else's.
So, as an investment, Ferrari must repay Lynch for his contribution, or rather investment, through his own methods, such as tax exemption policies after he comes to power.
