  We analyze the $\alpha$-$^{12}$C inelastic scattering to the $0^+_2$ state of
$^{12}$C, the Hoyle state, in a fully microscopic framework. With no free
adjustable parameter, the inelastic cross sections at forward angles are well
reproduced by the microscopic reaction calculation using the transition density
of $^{12}$C obtained by the resonating group method and the nucleon-nucleon $g$
matrix interaction developed by the Melbourne group. It is thus shown that the
monopole transition strength obtained by the structural calculation is
consistent with that extracted from the reaction observable, suggesting no
missing monopole strength of the Hoyle state.
