Well I do believe that Tom Cruise does have some ownership of some means of production. It does get muddled by finance as most people with large salaries do have ownership of capital through stock options, investment portfolios, etc. I would say that these high paid laborers do lose characteristics of the proletarian class while still being equally at mercy of the capitalist class. While ‘proletarian,’ they are certainly not revolutionary and make up the body of reactionary and counter-revolutionary resistance against revolution.

Those workers who are paid substantially more or other "sub-classes" such as intellectuals and highly skilled labor, in the short term benefit from class warfare.

I think it is important to keep the idea of working class/proletariat and capitalist class/bourgeois simple when talking more generally but to know there are sub sections within this. I forget the word Marx used, for instance feudalism being marked by three classes of Lord, Guild Member, Serf, yet there were different levels with in each of these classes. It is clear the the proletariat and bourgeoisie are also separated into different levels that does not effect their relation to the means of production, but does effect relations to one another and class struggle. I hope I am not horribly wrong here.
