revenue from tax collections hit an all time high in 2018 and expected to be higher in 2019. we don't have a revenue problem, we have a spending problem.
Your first statement is misleading. Here are the annual revenues for taxes.
2014 = 3.02 trillion
2015 = 3.25
2016 = 3.27
2017 = 3.32
2018 = 3.34 (estimated)
2019 = 3.42 (estimated)
Obviously 2018 and 2019 are estimates, not actual. So for the last several years, revenue has been flat.
We do need to cut back on the spending. The biggest slice of the spending pie is on military/defense. We should start there. One of the other big areas is healthcare. Obama made an attempt to tackle that problem with very little to no support from the GOP. I would like to see the Democrats take the Senate and the WH so they can address the healthcare problem in this country.
