You are right but this is a very complex matter. To put simply I'd say they want to have their cake and eat it too! You see, lowering interest rates would help the US economy start getting out of recession, it will help attract investors in the production sector and create jobs. Which are all positive speculations. But the US economy has turned into a debt based economy. Even the government functions like that. But when the government creates debt, it needs to be able to "sell" that debt to other countries and have them bag-hold that debt (the bonds the US gov. sells).
Now the problem is that with the World Order being established in the multi-polar world, other nations are not as willing as before to buy the US debt. For example China has already dumped IIRC $400 billion of those bonds.
The interest rates is what encourages them to continue bag-holding the bonds and maybe buy more (like Japan buying more). If they cut rates, not only the dump may speed up but also they will have a harder time convincing other countries to buy more of the US debt. That means more domestic inflation. That will discourage investors again!
We know that the US government is playing a well-defined selfish role right now. As I said before, the current US government is playing a greedy role right now. They don't care about anyone in the world. They just want to be the more powerful and best economic holding entity in the world. They are fetching a very big investment from the Middle East, but in return, the Us is giving no guarantee of safety to them, as we have seen a recent blast in Qatar, we know that during the recent visit of Trump, how much Qatar has invested and raised for the US, and even Qatar has gifted $400 million worth of airplane to the Trump. But still, there is no hard action taken by America against Israel. I believe that the US just doesn't care.
P.S. Trump's involvement in crypto space is not an investment type of involvement, it is more like a scammer tactic. They created useless shittokens (which requires virtually zero investment) and sold it to gullible people and made millions.
Honestly, I was about to say the same thing, but you said it, and I really agree with you here. Shitcoin like "Trump coin" and "milenia coin" were put in the market with zero use case, which wasted billions of dollars as a result, and nothing else but yes, the Trump family has made a big amount of profits from it. Billions of dollars were wasted, but at that time, the large amount that was heavily invested in the Trump coin could have been used for some other good developing projects and well-idea-based crypto projects, then the market condition could have been something else. What do you say?
