This is true. The almighty founding fathers purposefully put in several requirements for somebody to vote, most only being removed relatively recently, and with far too much effort and blood. Essentially, in order to vote, a person had to be a landowner (have money), be white, and be male (might have been some other restrictions, can’t remember rn). This excluded much of the population, by design. This is because the Constitution was not designed by the filthy commoners, but by the wealthy older white men.
