Social Security is not an entitlement... I've paid it for 3+ decades.
No no no. For 3 decades you paid for the people on the program to collect their benefits. After you retire, you will want people working to continue to pay SS taxes to fund your benefits.
I wish it was a true savings plan where they taxed you, piled up those revenues into an account, and then paid you back out of what you paid in. It has never worked that way, and it is too late to switch over (because we have already promised huge payments to people like you whose tax payments over the years have already been spent - so if we use future taxes to create true savings for subsequent retirees, then there is nothing to use to pay your benefits).
The "problem" is that we only taxed people $310 PER YEAR in the 1950s and 1960s and 1970s, and then when those people retired and collected benefits we paid them $1000 per month (because we were collecting $250 a month from 4 workers and could afford to pay that level of benefits out of current tax revenue). When we upped the SS taxes in 1983, we upped the benefits and spent that money currently on income tax cuts for current workers instead of saving it to pay benefits in the 1990s and 2000s. So in the 1990s and 2000s, we paid big benefits to Grandma to let her live in her own apartment in Arizona, and saved nothing to use to pay the Baby Boomers in their retirement. So now, instead of having 4 workers pay $250 per month to pay a retiree $1000, we have 2 workers paying in $250 per month (because there are fewer workers per retiree than before, and because real wages haven't moved in 40 years), but we are paying the retirees $1500 or $2000 per month.
We ran a tiny federal budget surplus in the late 1990s in large part because the large cohort of Baby Boomers were in their working years (ages 30s and 40s) and only the relatively small cohort of Depression era babies were retiring. Once the Baby Boomers started retiring in 2011 and the smaller Gen X and Gen Y were the prime working cohorts, the math swung hard against the system. There will be another "window" to fix things when the Baby Boomers finally die off, the smaller Gen X is retired, and the large Millenial cohort is working.
And now you understand why the federal budget is in perpetual deficit and why only by tweaking SS can you go from deficit back to surplus without raising taxes to levels that seem politically unsupportable. Albeit rates likely far below where they were in the 1950s - 1980s before the Reagan tax cuts. If we are going to "Make America Great Again", are we willing to go back to the marginal tax rates that were in effect when America "Was Great"? Top tax rate on investment income back then ranged between 70% and 91%. Back then we built the Interstate Highways and sent men to the moon. Now with rates in the 30% range we can't afford to fix roads, rails, bridges, etc. But we want to be "great" on the cheap I guess.
