How bloated is the Office of the President?

The Office of the President (OP) is perhaps the most bloated agency in the whole government, from the Executive to Legislative to Judiary branches. Consider the following:

1) The OP has under it 21 Cabinet Secretaries (heading the 21 departments).

2) There are around 40 Presidential Advisers/Assistants/Consultants, almost all of whom are also called "Secretaries"; ie, Cabinet level with no cabinet portfolio.

3) Other offices under the OP:
a. Commission on Higher Education (CHED)
b. Energy Regulatory Commission (ERC)
c. Housing and Urban Development Coordinating Council (HUDCC)
d. National Anti-Poverty Commission (NAPC)
e. National Security Council (NSC)
f. National Youth Commission (NYC)
g. Presidential Legislative Liaison Office (PLLO)
h. Presidential Management Staff (PMS).

Their budgets though, are not as big as the regular line departments, except CHED.

4) The Executive Secretary (aka "Little President") has 3 Senior Deputy Executive Secretaries, 4 Deputy Executive Secretaries, and 3 Assistant Executive Secretaries!

5) The OP's Communications Group is also bloated with 10 UnderSecretaries, 5 Assistant Secretaries, 1 Secretary General, 1 Executive Director, 10 Directors.
