Social Security is a major issue in the presidential election. First of all, the vast majority of Americans either collect Social Security benefits or plan to do so in the future. And it's no secret that Social Security isn't exactly in the best financial shape right now. Here's what you need to know about both candidates' plans for Social Security and what's likely to actually happen.

Donald Trump's stance on Social Security

In contrast to most other republicans, Donald Trump doesn't want to cut Social Security. However, his solution to Social Security's funding problem isn't to raise taxes or reduce benefits for the rich. Instead, Trump feels that his tax cuts will stimulate the economy to a point where Social Security's problem will take care of itself.

He certainly makes a valid point. Job and wage growth would undoubtedly lead to more money flowing into Social Security's trust funds as a result of the higher payroll taxes that would be collected. Even so, there are a few issues that critics have with Trump's logic:

• No president can guarantee economic growth -- not even with massive tax cuts.
• We're not worried about Social Security over Trump's hypothetical four- or eight-year presidency. In fact, Social Security can afford to pay all promised benefits through 2034. We're worried about Social Security 20, 30, and 50 years from now and therefore need long-term fixes.
• According to a model by the Urban Institute, even if Trump manages to boost GDP growth to 3.4% per year in perpetuity (the historical average), it would simply delay Social Security's financial problems by 30 years, not solve them.

To be fair, this isn't the only way Trump has suggested to fix Social Security. For example, Trump has suggested that we cease foreign aid to countries that "may want to kill us" and direct that money to Social Security instead. And, he has pledged to eliminate fraud and waste within the system. Finally, Trump's campaign has said that after his tax plans boost the economy, he would revisit Social Security's funding issues.

It's entirely possible that if Trump gets elected, his tax cuts will boost the economy enough that Social Security runs a surplus, and that his fraud elimination saves taxpayers a lot of money.

Hillary Clinton's plans for Social Security

In contrast, Hillary Clinton's plan for Social Security is more traditional. Essentially, not only does she not want to cut benefits, she wants to expand them, particularly for widows and family caregivers. To pay for it, she wants to increase Social Security taxes on the rich.

As of 2016, only the first $118,500 in wage income is subject to Social Security tax. While we don't know specifics yet, Clinton wants to raise, or possibly even eliminate, this cap.

How feasible is Clinton's plan? I've written before that the majority of Americans on both sides of the political spectrum, in all age groups, and in all income brackets agree with the following statements:

• Social Security is important to preserve for future generations.
• I don't mind paying taxes for Social Security.
• I wouldn't mind a tax increase if it strengthened Social Security.

So, it appears that the American public would embrace Clinton's solutions. However, if elected president, she'll need to get Congress to play ball, which is no easy task.
