The reasons are clear.

(1)They need money to make the system (even if it is outsourcing)

(2)The discrimination occurs because of IT digital divide.

(3)The ambiguity over where responsibility lies when some troubles happen.

"Sharing the patient pains or getting claims is better than thinking the annoying"

It is worth the cost correctly.

In addition, we shouldn't forget

(4)Cutting the numbers down dynamically

For example, the automatic ticket gate system of the railroad should have started earlier, but various oppositions (initial investment cost, labor union) had interfered with it for a long time.

"The system development" is surely something like destruction work for the vested interest, and it may be said that it is terrorism to destroy "the biggest happiness of the greatest multitude".

My Stress becomes bigger because I can image a systems construction method.
