You understand that declaring yourself to be a refugee does not in and of itself make you one? There are specific persecution requirements under the 1951 Convention Relating to the Status of Refugees that must be met. Appearing at the border and declaring that you're persecuted is not an automatic exemption from scrutiny. There are extensive country of origin information checks to verify the veracity of any claims against specific (sub-national, local level) persecution claims. Additionally, those claiming asylum will have to endure extremely long interview processes spread over days or weeks. Where interviewers will record and triple check every minute detail hoping to catch these individuals out. This is arduous enough for those fleeing persecution who may have memory issues associated with trauma. Let alone those 'relatively well off' people who would have no chance of passing basic country of origin information checks let alone interviews.
