The class

No. They(the professionals like the doctors and lawyers and high executives) do not fit into the category of petty bourgeoisie who though living on wages including a share (little bigger crumb) in the non-capitalized surplus and harbor the illusion of being part of the ruling classes.  Their vested interest gets aligned with the interest of ruling classes to whom they have sold their conscience. The interst of ruling classes become their interest. They are  under illusion of accumulation ignorant of the fact that in capitalism only capitalst can accumulate and others howsoever high wage earners they may be, are only under the illusion of accumulation as their investments give them the illusory feeling of ownership byuy poting their ill-earned or un-earned income on disposal of the corporate.  They could be broadly placed in the category of  Andre Gunder Frank's category of lumpen bourgeoisie(1972), derived from Marx's notion of Lumpen proletariat in the "Eighteenth  Brumaire of Louis Bonaparte", translated in the present context of the global, imperialist capital that has lost geo-centrality.This strata by definition and by circumstances come under the category of working people as they earn their survival by mental/manual labor. The are working class in-itself (Marx: Poverty of Philosophy) and not only are incapable of becoming class for itself  but are biggest hindrance in the way of  the under-privileged working class from becoming class for itself.
