Oh, cry me a river! Are DU-folk recycling 1970s-vintage feminist whines?
Higher price clothing? Higher cost dry cleaning? Go for plainer styles and fabrics, and avoid designer labels.
Women's "Plus" sizes cost more but men's big & tall sizes do not? BS! And I'm 6' tall and used to weigh close to 350 lbs., so I'm contradicting from experience. One thing I've noticed in doing running/walking races the past couple of years is that while race T-shirts are generally included in the registration fee, there is usually a surcharge for sizes XXL and larger (for men and women).
Don't like the higher prices for women's razors and shavers? Buy what men buy: nobody will notice; the quality will probably be better.
But let's get back to something more fundamental: 1.) taxes are charged by government, not private businesses; 2.) many/most taxes are unavoidable (without risking fines and imprisonment); 3.) if the higher prices for women's products were indeed not due to the higher cost of producing those items, somebody by now would have made a huge fortune by undercutting those artificially high prices, and forced competitors to follow suit or lose a lot of business.
Equivocation and economic ignorance!
