It's not anti-Marxist, Engels was Bourgeois and allocated profit to fund revolution. If you can assist in communal development by hooking into the profit motive of the global economy, that's okay.

In Imperialist countries there's very little difference between wage-laborers and the petty-bourgeoisie "proper" (as in, propertied), it mostly boils down to lifestyle choice, risks and gambles.

In many economies, there are nationalities that are gate-kept from the wage-work ladder, these are the small business (often immigrants) selling food at metro stations or outside stadiums, the (historically) Black windshield washers, shoe-shiners, and other such "hustler" work. These are indeed petty-Bourgeois relations but they are enforced in a semi-formal, lumpenized form. The bottom of the petty-Bourgeoisie can be lower economically than minimum-wage work, because even minimum-wage work can be turned into a privilege (Diploma, GED).

Marxists need not be Proletarians, however, their overall life's work needs to be working toward the eventual emancipation of the Proletariat (exploited segment of the workforce).

Most Imperialist countries, have little to no Proletariat "proper" (exploited laborers, realistically paid less than the global average of labor or around less than $5-6 USD). Un-exploited wage-laborers, often referred to labor-aristocracy or (dated) "servants", make the bulk of an Imperialist country's workforce.
