You claimed that 15$/hr is required
No, I said $15/hour should be the federal minimum wage.
Demanding increased minimum wages has never worked to resolve poverty
False:
Researchers determine that regardless of the scenarios, a federal minimum wage increase would reduce poverty among all race and ethnic groups. Considering this wage increase would likely impact 56 million workers, it has the potential to bring great financial relief to families who need it most.
According to the Congressional Budget Office, the $15 federal minimum wage would have boosted the earnings of low-wage workers and decreased poverty. In its absence, a national policy agenda focused on raising wages is still urgently needed.
A new Center for American Progress analysis shows that setting one fair minimum wage for all workers across the nation, specifically tipped but also for disabled and temporary teenage workers, will help alleviate poverty, sustainably grow the economy, and advance gender, racial, disability, and economic justice.
Eight states have already eliminated the tipped minimum wage entirely.2 This analysis finds that in those states, workers and businesses in tipped industries have done as well as or better than their counterparts in other states over the years since abolishing the subminimum wage. Meanwhile, 16 states use the federal tipped minimum wage of $2.13 per hour. Another 26 states and the District of Columbia have a tipped minimum wage higher than $2.13 but still below the prevailing regular minimum wage.

Believe it or not, just declaring things doesn't make them true.
