The OP reflects a disturbing lack of knowledge about Basic Government Stuff - Stuff that every working adult should know implicitly.
Social Security is NOT PART OF THE FEDERAL BUDGET! They count it for some purposes, but income tax dollars CANNOT be spent to supplement Social Security, because the program is unconstitutional and the only way it got through the Supreme Court's scrutiny was to ensure that it is separately funded. It is funded by PAYROLL taxes (as is Medicare), that are collected and figuratively put into a trust fund that is reserved for SS and nothing else. In the years when Boomers were at their peak earnings, the trust fund was overflowing with money, so Congress "borrowed" some of the surplus to fund current year expenditures, and is now paying that back.
The SS trust fund will never run dry, although if nothing were done to shore it up, it would be depleted in 8-10 years. Congress won't let that happen, and will convene a special committee of some sort to adjust things and make it solvent again. The maximum salary subject to the tax will either be greatly increased or the max will be eliminated altogether. We'll see. But don't fret about SS running out of money because (a) it won't, and (b) even if it did, that wouldn't stop SS payments, merely change it to a pay-as-you-go proposition which would decrease payments by about 20%.
The Federal Minimum Wage - also unconstitutional - must be irrelevant in order to do no harm. That is to say, it must be so low that it really makes no difference except on the extreme margins of the economy.
To illustrate the point, the Federal MW is irrelevant where I live. Employers MUST pay at least $10/hr or literally no one will work for them, except possibly retired bastards like me who are looking to get out and see some people when they are not taking naps. Therefore, if the Federal MW were increased to $10/hr, that would be totally irrelevant in my area.
Even the Democrats in Congress know this, which is why they have made no serious attempt to implement a $15MW despite talking like they support the idea. And when they do draft proposals, it's not for a $15MW TOMORROW, but implemented slowly over a period of at least five years.
A $15 MW would have no impact in big cities, but a significant impact is large portions of the country, where entry level wages are the lowest. The $15MW (if implemented immediately) would cause a lot of small business failures, job losses and/or reduction in hours for many people, and people working "under the table" in unprecedented numbers.
A "high" MW wage is a path out of poverty for NOBODY. That path comes from getting better jobs, getting promotions, learning a skill or trade, or starting your own small business. And this is where our immigrants have a lot to teach our native-born poor people, who fail to see the abundant opportunities that are out there.
