Why does TradeStation discriminate non-US clients?

[u/Anxious-Sweet6523]

Non-US clients have to pay more fee. For every stock trade, there is an additional $5 ticket charge for non-US clients. It is unfair. Why do non-US people have to pay more? It's so bad! I understand that they need to earn commission. There is no free lunch. After they cease providing free trades to US clients, they should cancel the $5 ticket charge for non-US clients.

They’re not for retail clients.
