Secure online apps are end-to-end. You could have some box in the middle
copying every bit in both directions and not lose anything. In fact you
do: it's called your ISP. Wireless connections are no less secure than
wired in this sense because they only affect the local link.

Using WPA protects you from intruders piggybacking on your bandwidth or
injections into local trusted networks, and of course general snooping,
but any serious online application with security requirements is going
to use application-level end-to-end security. The dangers in this case
aren't from snoopers, they're from careless app design, poor admin
practice on the server end, weak passwords and poor host security in the
client, etc. WPA doesn't solve any of these issues and using a wired
connection doesn't either.
