杨国忠确实善于敛财，而且他做的脏活一般人都不愿意做，这也是唐玄宗用他的原因，至于杨贵妃，她当然不用为安史之乱负主责，但是死了也不无辜可怜，毕竟杨国忠从各地敛来的财富很大一部分是在维持唐玄宗杨贵妃的奢侈生活，她是受益者
It's true that Yang was good at wealth and that he didn't want to do his dirty work. That's why Tang was the one who used it. As for your wife, she certainly didn't have to take the blame for Anxie's troubles, but she was not innocent. After all, a large part of his wealth from everywhere was to maintain the luxury of her life, for which she was the beneficiary.
