more than 比较分句后的成分剖析？

特朗普说的原话：

We pay more than anybody else by far have for many many years.

多年来大家支付的钱比其他其他人都多。

by fa 副词，到今天为止，能理解。

但by far后面的have是什么问题呢？

为何不去掉have, 即 We pay more than anybody else by far for many many years.

这个have作何成分？

have （paid). than从句谓语为目前完成时，省略paid, 只保留操作词have。这就是比较分句的动词替代形式（也可理解为省略）。
