Okay, no, youre operating off of faulty logic. Everyone is going to be jacking up their prices the same amount, because they all can and they all want to maintain income. They will move in a coordinated fashion to raise prices as they always have historically done, whether that coordination is merely born of the same interests or active conspiracy.
Also even within neoclassical logic demand would increase as people have more money, the supply would stay the same, so prices would equalize higher.
This is the type of message needed to inspire good democrat turnout
