It's the kind where it's so common you think of one every day.
It's also not that much, 100K USD has never been lower in value, so that trend is moving in your favor too.
That's why they say ideas like this are worthless, but they're wrong.
In perspective, though, when a company pays somebody 50K it really costs the company about 100K anyway, and there are companies all over the place where that's what they pay people who are not expected to produce anything at all. We all know how many bullshit jobs there really are.
So there's lots of people every day who have ideas more wortwhile than their actual job.
Every once in a while it's a million dollar idea but it can be kind of hard to tell and usually slips under the radar.
Since it requires a different type of action to get the ball rolling either way, 10X remains just as far out-of-reach as an uneconomical venture.
Now the 100K amount is a good example benchmark, but you can also think about things like 250K etc.
