Sure, corporations are lame and if you work for one you're a cog in a machine, I agree it can suck. But it's crazy to suggest that this somehow invalidates democracy.
The first job of a functioning government is to establish a monopoly on violence and prevent it from being used against the people. Sure there are times when modern democratic governments fail at this but they do a pretty good job of making sure that Jeff Bezos can't literally murder his lowly serfs when they get out of line. He can take their jobs but he can't take their lives and that's a far cry from how things worked in the Inquisition.
When you make spurious claims like implying that we don't live in a democracy, you're dishonouring the millions of people throughout history who wrested power away from the kings and warlords of the past, bit by bit, and built a system which at least places a few limits on its most powerful members.
