Forget about 3000 a month, some people have very 'simple' businesses like clothing retail and earn way above engineers salary, which is really what a lot of entrepreneurs want at the end of the day. There's nothing new or innovative about these ideas other than maybe the right branding or location, but it goes over the tech industry's heads here because their venture capitalist overlords are telling them to work on unicorn ideas because they want to make billions, when most founders would be content with just making millions.
Or maybe VC's actually want to change the world and don't care about profit? I'll just take the money, thanks.
