That is simply not the case and lawmakers can make any kind of law to shape the society how we wish. If leveraged buyouts are creating problems for the country, then it’s totally valid to make them illegal in certain cases.
And yes, I do think laws should be based on consistent principles. I'm surprised you consider that a controversial point...
No one is worried about the bank making the loan in this situation. They are concerned that PE is buying up large parts of the economy using debt they aren't responsible for, which makes them irresponsible owners because they do not face consequences when the moves fail
Again, isn't that entirely the bank's problem? They're responsible for the debt if the company can't pay it, right? I agree on the surface this seems like a bad deal for the bank, but what makes you think you know better than the bank so much so that they shouldn't even be allowed to take that risk?
