Idk, it really depends on how strong your affiliated lobby group is. The average voter competes against the Havard Kennedy or Oxford etc. graduate-led super PACs, lobby groups, whatever. So yes, it gets easier to believe "democracy" doesn't work or exist. However, lobby groups and elected officials wouldn't be a thing if we (society) didn't have the impetus, burden, or requirement to collectively believe (or have others do) that a thing such as democracy does exist. So if someone has a requirement to make you believe something, you have to ask why? In most cases you can acquire some kind of resolution using that.
