The left more than anything else hate the Trump because he's a billionaire

Wake up, angelo - he's NOT a billionaire. He's in debt up past his eyeballs to Deripaska, Firtash, MBS and god only knows which other despots.
besides he being a buffoon.
Yeah there is THAT. But Bush was a buffoon and didn't attack the Constitution - at least not directly.
It's reported that Bloomberg has ten times Trumps worth.
If that is "reported" it's totally made up. Not true at all. That would put him in ten times as much debt as Cheato is. Ten times negative 100 million would be negative one billion, and that would be a conservative estimate. Trump is likely in nearly a billion dollars of debt - most of which will be forgiven if he can deliver Ukraine unto Putin.
That most certainly must get up the socialists noses. What, a president coming from the privileged classes?
You really need to educate yourself better - Bloomberg's dad was a book keeper for a dairy. Didn't come from a "privileged class" by any stretch.
He made his own billions. Trump inherited and squandered 400 million dollars he got from his dad, using it only to dig himself deeper in debt.
Wiki:
In March 2009, Forbes reported Bloomberg's wealth at $16 billion, a gain of $4.5 billion over the previous year, the world's biggest increase in wealth in 2009.[35] At that time, there were only four fortunes in the U.S. that were larger (although the Walmart family fortune is split among four people). He had moved from 142nd to 17th in the Forbes list of the world's billionaires in only two years.[36][37] Subsequently, Forbes reported his wealth at $22 billion, then $31 billion, then $43.3 billion, and ranked him 11th-, then 10th-, then 6th-richest in the U.S.[23][38][39] As of November 2019, Bloomberg was the 14th richest person in the world, with a net worth estimated at $58 billion.[3]
If he spends a tenth of that, only Putin and MBS can save Cheato from a humiliating drubbing. So far he has only spent about 200 of his 58,000 millions. What's $200 to someone with $58k in their pocket? Chump change.
