NO economy can sustain itself for very long if it is so heavily service based as we have become.
So, who pays for “Public Sector” employment? Public Employees?
Who pays for “Service Employees”? More Service Employees?
Eventually, you run out of the actual reason for a Service based economy like the one we find ourselves in. The pathetic thing is, people like yourself, have no clue what will eventually happen, nor do they care.
