No. The Supreme Court long ago decided that merely being a taxpayer -- much less "any American" -- does not give standing to challenge laws. Otherwise, "any American" can sue to overturn any law at any time.
But George76 answered the question. Someone who actually took out student loans is directly affected by this law, rather than affected in a general sense.
HAHAHA...you misuoating SCOTUS. Do you work for Soros?
Scotus explicitly said tax payer has no standing to challenge an exiting law.
Now get your brain in higher gear. Ther is NO LAW PASSED to forgive student debt. Congress has passed no such bill and signed into law by POTUS. This is strinctly done by Biden with Executive Order.
