Except that the N+1 economy is now bigger with +1 demand for johns labor; thus it is actually increasing. Further, there is a +1 supply for production and export making the economy more competitive and productive overall. Economists used to believe that many things were zero sum, (ie if England allows French cheese imports it will be at the expense of British cheese producers. Yet often allowing imports and increased trade leaves both France and England richer as consumers in both places value the additional selection and the competition lowers prices or foreign items can charge a premium for their novelty). Immigration is similar; it’s not zero sum. Blaming this on a cynical political motive to create a voting block is contrary to the history of commerce and global trade and also contrary to your own analysis. It seems to me that the party most opposed to immigration is also the party that had been driving inequality by 1. Promoting globalization while also decimating the social safety net that would ease the transition, 2. Shifting to regressive taxation on sales while drastically lowering taxes on capital and its accumulation i.e. inheritance taxes. 3. Destroying any bargaining power for workers and employees and resisting minimum wage increases. I could go on and on.
