The grouping of "leftists" as a singular group doesn't make sense. The economically left person might say that work visa programs are just ways for capital to cheapen labour by exploiting foreign workers who have less opportunity to not be exploited. The socially left person might say that work visa programs provide diversity and opportunity to people from less developed countries.

Similarly, an economically right person might say that work visas are necessary to make certain kinds of labour affordable for business owners. A socially right person might say that work visa programs are abhorrent because they bring foreigners into the country.

"Left" and "right" are broad tents - they're sure to contain conflicting or mutually exclusive viewpoints on some issues.
