He invented 34 felonies based on 1 payment. That's like if you buy 1 stolen car or something on layaway you can get sent up for 60 months' or whatever your payment terms were.

No - he was charged with 34 felonies based on 34 separate instances of falsified documents. If you buy a stolen car on layaway you can't get hit for sixty charges, because you are not committing a separate crime each time you make a payment (assuming your mode and method of payment are lawful). If you steal someone's debit card with a thousand dollar balance and use it 60 times, though, that can be 60 separate instances of wire fraud.

We have an unscrupulous DA arresting the opposition party leader.

In a situation where there is prima facie evidence that the opposition party leader has committed a crime. In fact, there's an excellent case that he committed a misdemeanor. There are legal arguments over whether it's appropriate to charge for felonies, or whether the statute has run. But Trump has almost certainly committed a violation of the NY Penal Code....which is something you'd have to have present for a Red State DA to be able similarly indict.
