14U I agree with what you say re Wings and his 4 Houses after 9 years in RBA.
Anyone can buy 4 houses to let on 90% Mortgages.
10 Years of a full RBA Salary wouldn,t buy my house in the South East of UK.
By all accounts RBA have not had a payrise for 10 years and just like so many other Airlines they are taking full advantage of the Pilot situation and IMHO is not a company to give up a job to join but if unemployed then it is better than starving.
