For 2021, 2020 and 2019, the total contributions you make each year to all of your traditional IRAs  and Roth IRAs can't be more than:

$6,000 ($7,000 if you're age 50 or older), or
If less, your taxable compensation for the year

Charitable donations will only lower your taxes if all of your itemized deductions are higher than the standard deduction set for that tax year.

Big companies drove the 2017 Tax and Jobs Act, but did not commit to any specific wage hikes, the Center for Public Integrity found

Companies used the tax break to buy over $trillion in stock buybacks instead of investing in capital or people. Good points about fiduciary responsibility to benefit shareholders...Really fucked up.
