Easy, poor people don’t really contribute to the tax base, rich people pay for almost all the income tax, sales tax and property tax. Poor people are the receivers of most government benefits and programs, which make them a net expense revenue wise.

In the USA, the top 10% of all incomes account for 71% of all income tax, meaning the lower 90% only contribute 29%. Income taxes are governed by a power law (Pareto) where the very few account for most of the income.

The government as it is today and in most western countries is super progressive with its taxes and benefits for its population. I don’t think it’s good nor just to charge someone more simply because they have more, that’s pretty unjust, why do they have to pick up the slack and maintain people who don’t try to get out of their situation?

I come from a 3rd world country where we now have 2/3 generations who have grown living only on government welfare instituted by the governing party to earn their votes, while the productive few are choked by taxes and forced to leave the country, how is that just?

So yes, the government should prioritize the few that actually make money and try to get more of the population that way, as they are the ones funding government.

And of course you don’t want poor people from other countries which are used to live on government welfare also to eat through your welfare without contributing back, it’s actually a requirement in order to get the greencard, which you probably have no idea what it entails as I’m guessing you are a native born bleeding heart American liberal, otherwise you would have a more realistic view of the world.
