Venture capital, how do they manage to keep the scams going?

Are these venture funds really profitable? I hardly doubt it. I know of many who really do not have any sound business models yet they keep the scam going, with rounds of investments.

From what I was able to put together at the moment:

-Venture capitalism is about directing innovation into the direction Jewish Israelis desire. (if you do what they like to do, such as surveillance, vaccines etc.. you get the money, but if you want clean energy, cancer cure, etc.. you won't get the money)

-Control monopolies, with venture capitalism they make sure whatever new market dominating businesses are all under their control.

-Circular investments and directing the money to their other investments and companies. A lot of these entrepreneurs/start ups end up doing "rapid growth" which means giving a lot of money to Google/Meta/etc.. to put up advertisements.

But still, seeing all these failed business, or what should be a failed business like Uber/Tesla etc.. still going and seeing those major investment funds like Sequoia Capital making profits does not add up.

How do they fidget the numbers, who pays the tap eventually for all of these scams or maybe I am missing something. Anyone with any info? Thx.
