I think you'll find that you have it back-asswards.
If you are conservative because you want to conserve the wealth that you have -- which is usually the case -- then your life is fulfilling and comfortable because you are wealthy, not because you are conservative.
In addition, Conservatism is predicated on a relatively simple set of rules that don't require terribly much thought to live by (but require a lot of thought to justify, if you take the time). If you live by those rules, which is certainly easier if you are wealthy, then your mind is not "cluttered" with thoughts about the negative impact of your preferred policies on vast swathes of the population. And, yes, life is certainly more satsfying if you ignore the plight of your fellow man/woman/non-binary person.
Poor conservatives, by contrast, vote away their own opportunities for education and healthcare, to the benefit of rapacious corporations and billionaires. So, you're going to have to explain to me how that is a satisfying life.
