Finland, Sweden, Norway, Switzerland, Austria, Brazil, Chile, Mexico and Thailand each have active conscription [1]. The slippery slop you describe is far from inevitable.
You probably have no idea what you're talking about. Mandatory conscription (which I have personally served) is for a fixed term, so your livelihood is not tied to the army paying your salary. It's more of a semi-unpleasant mandatory intermission in your life plans.
Also, if you have decades of mandatory conscription then there is no slope to slip. Germany on the other hand is now on a slope, since they regress from a fully professional army back to conscription. How much down they will slip, remains to be seen.
I mean Singapore has mandatory conscription (for men), and I wouldn’t call it militarized. Especially not in comparison to some countries that are in the latter category.
