You may or may not do it, depending your discount rate.
Suppose being bee-sting free is worth H dollars/day to you, and the cure costs C dollars/day. As long as C/H < exp(-r( days until fully cured)) (where r is your discount rate), you'll buy the the cure.
Since r tends to be larger for the poor than for the middle class/rich, C/H is likely to be less than exp(-r(days until fully cured)), since the larger r gets, the smaller this constant gets. This is just standard econ, BTW.
