Titanic Facts: The Ship. White Star Line was the company that built the Titanic, and was owned by J.P. Morgan, an American tycoon. The cost to build the RMS Titanic was $7.5 million. RMS stands for Royal Mail Steamer. It took 3,000 men two years to build the Titanic.
Workers and employers pay for Social Security. Workers pay 6.2 percent of their earnings up to a cap, which is $118,500 a year in 2015. (The cap on taxable earnings usually rises each year with average wages.) Employers pay a matching amount for a combined contribution of 12.4 percent of earnings.
I do not believe it's a question of how many hours, but how much you can earn without it affecting your social security. I believe the the figure at present is $14,999.00. Any more than that can affect your social security. However, this is only for those who have retired early (starting at age 62).
