If he's successful, he'll take tax money from you and 300 million others and give it to candidates running for office.
If he's unsuccessful, you'll be a sucker and we'll all be a lot better off.
If a functional democratic system treats every candidate the same way in supporting i. e. financing after a certain popularity threshold is reached, who would that entity be other than an entity of the governing system in place?
As it is currently in the US, it's a hotchpotch of corruption destroying the very foundation of democracy. Can't even guarantee voting integrity across the board when some goons thinking doing the right thing are turning the screws somewhere in secret.
As for your aversion of using tax money used - where do you think is all that corporate money coming from? Who gets bilked and taken to the cleaner so the coffers of the "higher ups" in the pyramid - corporations as persons or individuals are overflowing?
Whenever you pay something, someone is taking a cut from it - at least you have the sales tax written on your receipt and there you know what is taken out.
I am happy that I can see my sales tax in roads getting fixed, public places kept in order, traffic light functioning, police working with gangs to keep the violence in check etc.
If you want to call me a sucker, look in the mirror to see one!
