<div>>>Charging interest being an okay thing, I would question. Given that<br>money in the time of the Torah's giving was primarily for emergency<br>situations and not for ordinary daily spending (and thus charging
<br>interest would be to charge someone in davka the time of his financial<br>struggles), and given that it is prohibited (at least Rabbinically) to<br>pay interest to a gentile (though we follow Tosoafot in not keeping<br>
this prohibition anymore), it seems difficult to say that charging<br>interest is morally fine. <,</div>
<div> </div>
<div>There cannot be a Rabbinic prohibition charging interest to a non-Jew, as the famous Taz says that Chachamim cannot prohibit something openly permitted by the Torah.</div>
<div> </div>
<div>See the Torah Temimah to Devarim 23:21 s.v. Omnam explaining why charging interest is indeed perfectly morally fine.</div>

<div>>>As for finding lost objects: to find and keep is the ordinary moral<br>way? Can one honestly suggest that there is no intrinsic moral problem<br>with finding and keeping? Is this idea not davka what the Torah comes
<br>to tell us is false? <<</div>

<div>This may depend on the Machlokes Rashi and Rambam on how to explain the prohibition of returning an Aveidah to a non-Jew, see Sanhedrin 76b and Tur Shulchan Aruch Choshen Mishpat 266:1<br><br> </div>
