Liberals/progressives/etc. want to increase taxes on things to discourage such items and/or activities. Examples include the NFA of 1934 which taxed firearms and certain safety equipment, huge taxes on cigarettes and alcoholic beverages, And of course there are the frequent demands for huge taxes on ammunition and sometimes on gasoline and other fossil fuels.
What this makes crystal clear is those same people use the tax system in a way that is consistent with a belief that there should be fewer rich people and more poor people. They place huge taxes on “the rich” and want to eliminate taxes on “the poor”. If they really wanted to reduce or eliminate poverty shouldn’t they be taxing it? Sort of like the demand for taxes on guns and ammunition to “pay for the costs of gun violence” shouldn’t there be taxes on poverty to pay for the cost of supporting the poor?*
* No. I’m not entirely serious about this. Only a little bit serious.
