People who say they can't do anything because they don't have money won't do anything even when they do have money.
こんにちは！
ご質問ありがとうございます。
ご質問について、いくつか言い方が考えられますが、例えば、
People who say they can't do anything because they don't have money won't do anything even when they do have money.
とすると、『[お金がない](https://eikaiwa.dmm.com/uknow/questions/1162/)と何もできないという人はお金があっても何もしない。』となります。
少し変えて、
If you wait until you have enough money to do something, you'll never do it.
とすると、『十分なお金ができるまで何かをするのを待とうという人は、結局何もやらない。』とも言えます。
参考になれば幸いです。
People who say they can't do anything because they don't have money wouldn't do anything even if they had lots of money.
この場合、次のような言い方ができます。
ーPeople who say they can't do anything because they don't have money wouldn't do anything even if they had lots of money.
「お金がないから何もできないと言う人は、たくさんお金を持っていたとしても何もしない」
